Starting HRT should bring relief, but what if you still have symptoms? Learn the 7 signs your HRT dose is too low, optimal hormone level targets, why the "wait and see" approach sometimes misses the mark, and how daily hormone tracking helps you optimize your dose in weeks instead of months.
You finally started hormone replacement therapy (HRT). You waited through the anxiety of making the decision, navigated insurance hurdles, and committed to taking your medication daily.
But weeks go by, and you're still having hot flashes. Your brain fog hasn't lifted. You're still not sleeping through the night.
Is the HRT not working? Is your dose too low? Or do you just need to wait longer?
Your doctor says, "Give it 3-6 months", but you don't want to suffer for half a year if your dose isn't right. You want to know NOW if you need an adjustment.
Here's the truth: Many women need dose adjustments within the first few months of starting HRT. The initial starting dose is often too low for optimal symptom relief. Although you may not be booked to see your doctor again for several months you may want to reach out sooner based on your Oova results. There's a better way. In this guide, you'll learn:
- The 7 signs your HRT dose may be too low
- Target hormone levels for optimal symptom relief
- Why the "wait and see" approach fails
- How to track your response in real-time (without waiting for doctor appointments)
- When to reach out to your clinician for a possible dose adjustment.

Understanding HRT Dosing: Why "One Size Fits All" Doesn't Work
When you start HRT, your doctor often prescribes a low dose to start with - aiming for the lowest dosage that resolves your symptoms":
- Estradiol: This may come in a pill, patch or vaginal ring.
- Progesterone: This may come in the form of a pill, patch or intrauterine device.(if you have a uterus to protect your uterine lining and prevent uterine cancer.)
This conservative approach makes sense, doctors want to start low and increase gradually to minimize side effects. But here's the problem:
The "right" dose varies dramatically between women.
Your optimal dose depends on:
- Your baseline hormone levels
- Your body weight and composition
- Your liver function and metabolism
- How you absorb medications (pill vs patch vs vaginal ring)
- The severity of your symptoms
- Your individual receptor sensitivity
What relieves symptoms for one woman may be completely inadequate for another.
Your Oova data allows you to monitor how you feel AND track your actual hormone levels - rather than relying on symptoms alone.
The Traditional Approach: Why Waiting 3-6 Months Doesn't Make Sense for Everyone
Patients often wait 3-6 months before adjusting HRT doses. The reasoning:
- "Hormones take time to stabilize"
- "Your body needs to adjust"
- "Symptoms may improve gradually"
But here's what research actually shows:
If HRT is going to work, you should see SOME improvement within 4-6 weeks. Not complete resolution, but noticeable change.
If you're still experiencing significant symptoms after 6-8 weeks, your dose may be too low, and waiting another 2-4 months won't magically fix it.
The "wait and see" approach means:
- Months of continued suffering
- Delayed relief from debilitating symptoms
- Potential abandonment of HRT entirely ("It's not working for me")
- Lost time you can't get back
Oova allows you to feel better sooner.
7 Signs Your HRT Dose May Be Too Low
If you're experiencing these symptoms 4-6 weeks after starting HRT (or after a dose that previously worked), your levels are may suboptimal:
1. Hot Flashes and Night Sweats Haven't Improved
What's happening: Hot flashes happen when declining estrogen levels make your brain’s temperature control center overly sensitive. As estradiol drops, the normal temperature “comfort zone” narrows, so even small changes can trigger a big cool‑down response and you feel a sudden wave of heat.
What to look for:
- Still having 5+ hot flashes per day after 6 weeks on HRT
- Night sweats disrupting your sleep multiple times per week
- Hot flashes are less intense but still frequent
Target: Most women need estradiol levels of 15-400 ng/mL to eliminate or significantly reduce vasomotor symptoms. If yours are lower, then speak to your clinician about considering a dose adjustment.
2. Sleep Problems Continue
Estrogen and progesterone both play important roles in sleep. Fluctuating or low estrogen can contribute to night sweats and awakenings, while declining progesterone removes some of its natural calming, sleep‑promoting effect, which can make it harder to fall and stay in deep, restorative sleep.
What to look for:
- Still waking up multiple times per night
- Difficulty falling asleep despite being exhausted
- Waking at 3-4am and can't get back to sleep
- Not feeling rested even after 7-8 hours in bed
Why it matters: Poor sleep compounds every other perimenopause symptom. If HRT isn't fixing your sleep within 4-6 weeks, an adjustment may be needed.
3. Brain Fog and Memory Issues Persist
What's happening: Estrogen receptors are concentrated in brain areas responsible for memory and cognition. Low estradiol = continued cognitive dysfunction.
What to look for:
- Still losing your train of thought mid-sentence
- Can't remember words you use every day
- Walking into rooms and forgetting why
- Difficulty concentrating on work tasks
- Mental "fogginess" that doesn't lift
What research shows: Studies indicate brain fog typically improves within 4-8 weeks of achieving optimal estradiol levels. If you're still struggling, your dose may be insufficient.
4. Mood Symptoms Remain Severe
What's happening: Both estrogen and progesterone affect neurotransmitters (serotonin, GABA, dopamine). Suboptimal levels = continued mood dysregulation.
What to look for:
- Anxiety that hasn't improved
- Depression or feeling emotionally flat
- Irritability and rage episodes
- Crying easily or feeling emotionally unstable
- Mood swings that feel unmanageable
Important distinction: Some mood improvement should happen within 3-4 weeks. If you see ZERO change, your dose is likely too low.
5. Vaginal Symptoms Haven't Changed
What's happening: Vaginal tissue is highly estrogen-dependent. Vaginal Dryness, vaginal skin fragility, and pain require adequate local or systemic estrogen to heal.
What to look for:
- Still experiencing painful intercourse
- Vaginal dryness hasn't improved
- Burning or itching sensations persist
- Urinary urgency or recurrent UTIs continue
Note: Vaginal symptoms can sometimes warrant both systemic HRT and local estrogen treatment (cream/suppository). If you're only on systemic, discuss the option of adding local vaginal estrogen therapy.
6. Joint Pain and Stiffness Continue
What's happening: Estrogen has anti-inflammatory properties and affects joint fluid production. Low levels can result in continued inflammation and pain.
What to look for:
- Morning stiffness that doesn't improve
- Aching joints throughout the day
- Difficulty with stairs or exercise
- Feeling like you "aged 10 years overnight"
Timeline: Joint pain typically improves within 6-8 weeks of adequate estrogen replacement. Persistent symptoms suggest suboptimal dosing or joint pain that may be unrelated to your estrogen levels. Follow up with your clinician if you’re not sure.
7. Energy Levels Haven't Improved
What's happening: Hormones affect mitochondrial function (your cells' energy factories). Low levels = continued fatigue despite adequate sleep.
What to look for:
- Still feeling exhausted all day
- No energy for exercise or activities you used to enjoy
- Needing excessive caffeine just to function
- Crashing in the afternoon
Red flag: If your fatigue is WORSE on HRT, this could mean your symptoms are unrelated to your ovarian hormones or for some women that your progesterone dose is too high. Discuss with your doctor if your symptoms persist or worsen on HRT.
Target Hormone Levels: What to Aim For
"Normal" ranges on lab reports are broad, and often inadequate for symptom relief. Here's what most women need for optimal results:
Estradiol (E2) Targets
Standard lab "normal" range: 50-350+ ng/mL (varies by day in cycle)
Optimal for symptom relief:
- Minimum: 50 ng/mL
- Target range: 15-450 ng/mL
- Upper limit: 450 ng/mL (higher may increase risks)
Important notes:
- Levels below 50 pg/mL rarely provide complete symptom relief
- Transdermal estrogen (patches, gels) often produces more stable levels than oral
- Timing matters: Check levels mid-week if using twice-weekly patches
Progesterone Targets
Standard lab "normal" range: Varies widely
Optimal for symptom relief:
- Oral progesterone: Check levels 2-3 hours after dose
Important notes:
- Too much progesterone can cause fatigue, depression, and bloating
- Too little won't protect your uterine lining or improve sleep
- If using synthetic progestin (Provera), these targets don't apply
The Problem with Single Blood Tests
Traditional approach: Check levels at your 3-month follow-up.
The issues:
- Hormones fluctuate daily (especially if you're still cycling)
- A single snapshot may not reflect your average levels
- Blood draws are expensive and inconvenient
- Results take days to get back to you
Better approach: Track patterns over time to see your average hormone levels and how they correlate with symptoms.
How to Track Your HRT Response in Real-Time
Instead of waiting months between appointments, you can monitor your response weekly, or even daily.
Method 1: Symptom Tracking
What to track daily:
- Hot flash frequency and intensity (1-10 scale)
- Sleep quality (hours slept, times woken)
- Mood (scale of 1-10, plus notes on anxiety/irritability)
- Energy levels (morning, afternoon, evening)
- Brain fog severity
- Physical symptoms (joint pain, vaginal symptoms)
How to use it:
- Track for 2 weeks before starting HRT (baseline)
- Continue tracking after starting HRT
- Look for patterns: Are symptoms improving, staying the same, or worsening?
- After 4-6 weeks, evaluate: 50% improvement = dose is probably right. 0-20% improvement = HRT dose may be too low or maybe your ovarian hormones are not the cause of these symptoms..
Method 2: At-Home Hormone Testing
The game-changer: Daily hormone tracking lets you see your actual estradiol and progesterone levels, without waiting for doctor appointments.
How it works:
- Test your hormone levels at home using urine strips (measures E3G and PdG, metabolites of estrogen and progesterone)
- Track patterns over time (not just single snapshots)
- See how your levels correlate with symptoms
Why this matters:
- You can advocate for dose adjustments with DATA, not just "I still don't feel good"
- Your doctor can see objective evidence your levels are suboptimal
- You avoid waiting months of waiting to find out the dose isn't working
- You can catch issues related to your hormone levels that might not be obvious from symptoms alone.
Oova's Perimenopause Kit lets you track estrogen and progesterone daily, so you can optimize your HRT dose in weeks, not months.
When to Consider a Dose Adjustment
Don't wait 6 months if you're still symptomatic. Here's when to contact your doctor:
After 4-6 Weeks:
- If you have ZERO symptom improvement
- If hot flashes/night sweats are still frequent (5+ per day)
- If sleep problems haven't improved at all
- If you're tracking hormone levels and they're consistently below target
After 8-12 Weeks:
- If you've seen only minimal improvement (less than 30%)
- If some symptoms improved but others persist
- If side effects are manageable but benefits are insufficient
Red Flags to Report Immediately:
- New or worsening side effects (severe headaches, chest pain, leg swelling)
- Unusual bleeding patterns (especially if postmenopausal)
- Signs of blood clots (leg pain, shortness of breath)
- Severe mood changes or suicidal thoughts
How to Talk to Your Doctor About Dose Adjustments
Many women feel dismissed when asking for dose changes. Here's how to advocate effectively:
Come Prepared with Data:
Instead of: "I still don't feel good."
Say: "I've been tracking my symptoms for 8 weeks. I'm still having 8-10 hot flashes per day and waking up 3-4 times per night. I'd like to discuss adjusting my dose."
If you’re tracking your hormones with Oova - you could also say “I’ve been tracking my hormones daily and here’s a visual of the range they’ve been running.”
Ask Specific Questions:
- "What dosing adjustments could we consider?”
- "How quickly should I expect to see improvement after adjustment?"
Know Your Options:
- Inquire about switching from oral to transdermal (often more effective)
- Consider getting a second opinion from a menopause specialist

Common Reasons HRT "Isn't Working"
Before increasing your dose, consider these factors:
1. Various HRT Preparations Affect Many Women Differently
Issue: Oral estrogen is metabolized by the liver and may not achieve adequate levels in some women compared to a patch.
Solution: Consider trying a transdermal (patch, gel, cream) for more consistent absorption.
2. You're Not Taking It Correctly
Common mistakes:
- Taking oral estrogen with food high in fat (increases metabolism)
- Not applying patches to recommended skin areas (absorption varies)
- Forgetting doses frequently
- Not rotating patch sites
Solution: Review administration instructions with your pharmacist.
3. You Have Thyroid Issues
Why it matters: Hypothyroidism causes similar symptoms to low estrogen, fatigue, brain fog, weight gain, mood issues.
Solution: Request thyroid testing if you haven’t had it tested in the last 12 months. Many women need BOTH HRT and thyroid treatment.
4. Your Progesterone Dose Is Too High
Issue: Progesterone can cause fatigue, depression, and bloating. Too much can worsen mood even if estrogen is optimal.
Solution: Discuss with your doctor if a lower dosage might be appropriate for you. Note - If you take no or too low of a progesterone dosage while taking estrogen you can increase your risk of uterine cancer so make sure to discuss this with your doctor for the correct dosing.
The Dose Adjustment Process: What to Expect
Once you and your doctor decide to change your dose, here's the typical timeline:
Week 1-2 After Increase:
- May notice some breast tenderness (estrogen side effect, usually temporary)
- Energy might improve quickly
- Sleep may start improving
Week 3-4:
- Hot flashes should decrease noticeably
- Brain fog starts lifting
- Mood stabilizes
Week 6-8:
- Most symptoms should be significantly improved (70-80% reduction)
- If still symptomatic, another adjustment may be needed
The Bottom Line: You Don't Have to Wait Months
The"wait 3-6 months" approach to HRT dosing may waste your time and prolongs your suffering.
Here's what you CAN do:
✓ Track your symptoms systematically from day one
✓ Monitor your hormone levels at home (not just at appointments)
✓ Evaluate your response at 4-6 weeks
✓ Advocate for adjustment if you're not seeing meaningful improvement
✓ Use objective data to understand your symptoms
✓ Don't settle for "this is as good as it gets"
You deserve to feel good, not just "better than before."
HRT should dramatically improve your quality of life. If it's not, your dose is likely too low, and you don't need to wait months to find out.

FAQ
How long should I wait before asking to increase my HRT dose?
Wait 4-6 weeks to see initial effects, but if you have zero improvement by 6-8 weeks, it's time to discuss adjustment. You shouldn't have to wait 3-6 months to find out your dose isn't working.
What if my doctor says my hormone levels are "normal"?
"Normal" lab ranges are very broad and can vary day to day. You may be in the "normal" range but still suboptimal for YOU.
Can my HRT dose be too high?
Yes. Signs include breast tenderness that doesn't resolve, bloating, headaches, mood swings, or heavy breakthrough bleeding. Very high estrogen (>200 pg/mL) may increase health risks. Work with your doctor to find the sweet spot.
Should I increase estrogen or progesterone first?
Your estrogen and progesterone levels need to be supportive of each other. Often a dose adjustment of one may result in adjusting the dosage of the other. Discuss with your doctor based on your primary symptoms and safety considerations
How often should I check my hormone levels on HRT?
Traditional medicine does not have a target hormone range but rather a goal to resolve your symptoms. Oova is actively working to help understand if there is a target range. Stay tuned!
Will tracking my hormones at home give accurate results?
Yes. At-home urine tests measure E3G and PdG (metabolites of estrogen and progesterone). While not identical to blood serum levels, they accurately reflect your hormone patterns and trends.
What if I’m on bioidentical HRT vs Synthetic HRT?
The core principle is the same: You need an adequate effective dose of hormone to relieve symptoms and protect long‑term health, regardless of the formulation. Bioidentical hormones (like 17β‑estradiol and micronized progesterone) are chemically identical to the main hormones your ovaries produce, while older synthetic options (such as conjugated equine estrogens like Premarin or synthetic progestins like medroxyprogesterone acetate/Provera) have different structures and receptor effects. Anticipated hormone levels may vary by HRT type so please discuss with your doctor if you have questions about your dosing.
