Trying to conceive, with your cycle on record
Log your period, any spotting and each ovulation test. The app keeps the dates in order and shows estimated fertile days, so you are not counting on your fingers every month.

You are most likely to conceive in the days just before ovulation and on the day itself. Ovulation often falls around two weeks before the next period, though it moves from cycle to cycle.
Her Good Days records your periods and test results and shows an estimated fertile window. It is a record and an estimate, with no guarantee in either direction.
A month in the log
When you choose "trying" in the cycle settings, your Log menu leads with these:
- Period: the first day matters most, because every estimate counts from it.
- Flow or spotting: light bleeding between periods is worth noting with a date.
- Ovulation test: positive or negative, with the time you took it.
- Mood and Sleep: trying can be stressful, and these show how the months feel.


Prenatal vitamins go under Medication, with a daily reminder if you want one.
Bringing it to a doctor
ACOG suggests seeing a doctor after 12 months of trying if you are under 35, or after 6 months from 35 on. If your periods are irregular or you have none, go sooner.
The doctor report prints your cycle lengths, period dates and test results, which is often the first thing a fertility appointment asks for.
Your data, kept close
Fertility and pregnancy entries are among the most sensitive things you can put in an app. Her Good Days never sells them or uses them for ads, notifications never say what you logged, and you can delete everything from settings. More on privacy.

Questions
When is the fertile window?
It is the few days before ovulation and the day of ovulation itself. Ovulation often happens around 14 days before the next period, but that varies, which is why the app shows it as an estimate.
Does the app predict when I will get pregnant?
No. It keeps your period dates, test results and notes, and shows estimated fertile days from your cycle lengths. It makes no fertility predictions and no promises.
Can I use it to avoid pregnancy?
No. The estimates are not birth control and should never be used to prevent a pregnancy.
When should we see a doctor?
ACOG advises seeing a doctor after a year of trying if you are under 35, after 6 months if you are 35 or older, and sooner if your periods are irregular or absent.
