A Guide to Tracking Your IVF Progress

One of the most disorienting things about IVF is the feeling that your most important medical experience is happening to you, not with you. Numbers are read out during brief appointments. Doses change without explanation. Results arrive as a single data point with no context. You're told things are "on track", but you can't see the track.

For many patients, the shift from passive recipient to informed participant is the single biggest improvement in their IVF experience. Not because tracking your data changes the clinical outcome; your doctor is monitoring the same numbers with far more expertise, but because understanding what's happening reduces the specific kind of anxiety that comes from not knowing.

This guide covers what to track, how to track it, what the trends tell you, and what to do with the information once you have it.

Why Tracking Matters

‍IVF generates a lot of data over a short period. During a typical stimulation cycle, you'll have three to five monitoring appointments, each producing follicle measurements for both ovaries and several blood values. After retrieval, you'll receive a series of embryo development updates. During FET preparation, you'll track lining thickness and hormone levels.

Most of this information is communicated verbally or in a brief phone call. Without a system for recording and reviewing it, you're relying on memory; and memory is unreliable when you're stressed, sleep-deprived, and managing daily injections.

Tracking your own data gives you:

• Context for each new result: Knowing that your estradiol was 800 today means nothing without knowing it was 400 two days ago and 180 two days before that. The trend is the information.
• Better questions for your care team: "My estradiol doubled in two days — is that the growth rate you expected?" is a more productive conversation than "Is everything okay?"
• A sense of agency: You can't control the outcome. But you can understand the process, and that understanding is its own form of coping.

What to Track During Stimulation

Follicle measurements

At each monitoring ultrasound, your care team measures the diameter (in millimetres) of each visible follicle in both ovaries.

What to record:

• Date of appointment
• Number of follicles on each side
• Size of each follicle (or at minimum, the range and the size of the lead follicles)

What to look for in the trend:

• Follicles should grow approximately 1–2mm per day
• Lead follicles approaching 18–22mm means retrieval is approaching
• It's normal for follicles to grow at different rates — you'll always have a range

Hormone levels

The key hormones during stimulation are estradiol (E2), LH, and sometimes progesterone.

What to record:

• Estradiol level at each appointment
• LH level (if provided)
• Progesterone level (if measured)

What to look for:

• Estradiol should rise steadily as follicles grow — roughly 200–300 pg/mL per mature follicle
• LH should remain suppressed (under 10–15 IU/L on most protocols)
• Progesterone should stay low (under 1.5 ng/mL) until after trigger

Medication doses

Your medication protocol may change several times during stimulation based on your monitoring results.

What to record:

• Medication name and dose for each day
• Time of injection
• Any dose changes and the date they took effect
• Trigger shot medication, dose, and exact time administered

What to Track After Retrieval

The embryo development timeline

After retrieval, you'll receive updates at specific milestones:

What to look for:

• The numbers decrease at each stage: this is expected biology, not failure
• Blastocyst grades: (e.g., 4AA, 3BB) indicate quality, your care team can explain what your specific grades mean
• If doing PGT-A: results typically take one to two weeks

What to Track During FET Preparation

Lining thickness

Your uterine lining is measured via ultrasound during FET preparation. The target is typically 7mm or greater, with a trilaminar (three-layer) pattern.

What to record:

• Lining thickness at each appointment
• Pattern (trilaminar or not)
• Estradiol level (correlates with lining growth)

Progesterone

Once progesterone supplementation begins (typically five to six days before transfer), your doctor may check your level to confirm it's adequate — usually above 10 ng/mL, though targets vary.

How to Track: Methods and Tools

The notebook method

Simple and reliable. A lined notebook with one page per appointment, recording date, follicle sizes, hormone levels, and any medication changes. Works well for patients who process information better on paper.

• Downside: You're relying on accurately recording numbers read to you verbally, and you can't easily visualize trends.

The spreadsheet method

A spreadsheet (Google Sheets, Excel) with columns for date, follicle count left, follicle count right, lead follicle sizes, estradiol, LH, progesterone, and medication doses. You can add a simple line chart for estradiol to see the trend visually.

• Downside: Requires manual data entry, and you still need to get the numbers from your clinic first.

The clinic app or portal method

A growing number of clinics now offer patient-facing technology that does the tracking for you — putting your results directly into a digital interface where you can view individual values, see trends over time, and review your full cycle history in one place.

At Pollin, the Pollin App provides this automatically. Your follicle measurements, bloodwork, and medication schedule are available the same day as your appointment. The My Fertility IQ feature visualizes your trends; follicle growth, and hormone levels, so you can see the trajectory across your entire stimulation without building your own spreadsheet. Your care team is available through secure in-app messaging if a number doesn't make sense.

This is the simplest method because there's nothing to record manually. Your data is captured at the source and presented back to you in context.

How to Use Your Data Without Spiralling

A necessary caveat: tracking your IVF data is useful when it helps you understand the process. It becomes harmful when it becomes a mechanism for catastrophizing.

Guidelines for healthy tracking

Compare yourself to yourself, not to others: Your estradiol, follicle count, and embryo numbers are specific to your age, diagnosis, and protocol. Comparing them to a stranger's numbers on a forum; who may be ten years younger with a completely different ovarian reserve, is not informative. It's distressing.

Understand the range of normal: "Normal" in IVF is wide. An estradiol of 1,200 on Day 8 can be perfectly appropriate for one patient and a concern for another. Your doctor interprets your numbers in context. If a result worries you, ask about it, but resist the urge to diagnose yourself.

Use your data to ask better questions, not to draw conclusions: "My estradiol doubled since last time — is that what you expected?" is productive. "My estradiol doubled so I must be overstimulating" is not.

Stop tracking if it's making things worse: Some patients find that seeing every number increases their anxiety rather than reducing it. If that's you, it's perfectly fine to let your care team hold the data and tell you what you need to know. There's no obligation to be your own analyst.

Frequently Asked Questions

Should I track my own IVF data?

It depends on how you process information. Many patients find that understanding their numbers — follicle sizes, hormone trends, embryo development — reduces anxiety and helps them feel more engaged in their care. Others find that detailed tracking increases stress. Either approach is valid.

What is the most important thing to track during IVF stimulation?

The trend in your estradiol level and the growth of your lead follicles are the two most informative data points during stimulation. Together, they indicate how your ovaries are responding to medication and how close you are to retrieval.

How do I know if my IVF numbers are normal?

"Normal" varies significantly based on your age, ovarian reserve, diagnosis, and protocol. Rather than comparing your numbers to a reference range, ask your care team at each monitoring appointment whether your response is tracking as expected for your specific situation.

Can I see my IVF results online?

This depends on your clinic. At Pollin, all monitoring results; follicle measurements and bloodwork, are available in the Pollin App the same day as your appointment, with trend visualization through the My Fertility IQ feature.

What should I bring to an IVF monitoring appointment?

Bring your questions; ideally written down. If your clinic doesn't provide digital access to your results, bring a notebook to record the numbers your care team shares. Wear clothing that's easy to change for the ultrasound.

How can I track IVF medication doses and schedule changes?

Record each medication name, dose, and injection time daily. Note any dose changes and the date they were made. At Pollin, your medication schedule is managed in the Pollin App with daily reminders, dose tracking, and real-time updates when your protocol changes.
