This tracker covers a sensitive category. Unhide is pattern-insight for self-improvement — never diagnosis, treatment, or medical advice. You'll be asked to confirm you understand this before your first entry.
When is your actual fertile window?
Track BBT, OPK, cervical mucus and cycle day — AI spots the pattern when your signs align.
Updated 26 June 2026
Your BBT rose on cycle day 16 in 3 of your last 4 cycles. On those days, your OPK result was 'peak' and cervical mucus was 'egg white' — and stress was below 4/…
Fertility signs don't always line up neatly. Your OPK might surge on one day, your cervical mucus might peak on another, and your BBT shift might come a day later. Tracking them together in one place lets you see how they relate to each other in your body — and whether things like stress, sleep or alcohol are shifting the timing. AI can spot when those signs converge, and show you what else was happening on those days.
6 fields. Done in 2 minutes each morning.
Fast enough to fit into any routine, specific enough to generate real patterns after 30 days.
Log, build, learn.
Log your signs each morning
Enter your BBT, OPK result, cervical mucus and cycle day — plus anything else that feels relevant that day.
Build a dataset across cycles
After a few cycles, you'll have a timeline of how your signs move in relation to each other and what else was happening.
Ask AI what's aligning
AI surfaces when your BBT, OPK and cervical mucus have aligned in past cycles, and what other factors were present on those days.
Why people stick with it.
4 things Ovulation / TTC (trying to conceive) reveals about you.
- Which cycle days your BBT typically shifts and what happened to your other signs that same day
- How your cervical mucus pattern relates to your OPK results across multiple cycles
- Whether stress, sleep or alcohol correlate with changes in your fertility signs
- What your own fertile window looks like when BBT, OPK and cervical mucus are viewed together
Here's what arrives at 30 days.
Illustrative — your analysis uses your own data.
AI looks at how your BBT, OPK results and cervical mucus line up across cycles. It might show that your BBT typically rises 1–2 days after your OPK peaks, or that egg-white cervical mucus appears most often on cycle days 14–16 when stress is low. It can also flag when sleep disturbances or alcohol correlate with BBT variation, so you know which readings to weigh differently.

People watching their own patterns.
This tracker is for people trying to conceive who want to see how their fertility signs line up across their cycle.
Common questions
Do I need to track every field?
No. BBT, cycle day and at least one other sign (OPK or cervical mucus) will give AI enough to work with. The more you log, the sharper the pattern.
What if my BBT is all over the place?
That's common. AI looks at the trend across days and flags when sleep was disturbed or alcohol was logged the night before, so you can see what might be skewing the reading.
Will this tell me when to have intercourse?
No. It shows you when your signs have aligned in past cycles. You decide what to do with that information.
Is this a substitute for fertility apps or ovulation predictors?
No. This is a personal dataset and analysis tool. It doesn't predict ovulation or replace medical advice — it shows you your own patterns.
How many cycles before I see useful patterns?
Most people start seeing correlations after 2–3 cycles of consistent logging, especially if you're tracking BBT, OPK and cervical mucus together.
Can I share this data with my GP or fertility specialist?
Yes. You can export your logs and AI summaries as a PDF or CSV to take to appointments.
