How do I know when I'm ovulating
The cycle calendar builds a forecast of ovulation and your fertile window from what you log: the longer you keep the calendar, the sharper the forecast.
If you've chosen the “trying to conceive” status, a conception forecast appears next to it, along with a form where you can enter readings — basal body temperature, for instance.
This is a forecast from your data, not medical confirmation of ovulation. If your cycle is irregular or pregnancy isn't happening, it's worth discussing with a doctor.
