Ovulation calculator
This is an estimate, not a measurement — actual ovulation can shift cycle to cycle. It works backward from your next expected period using the average 14-day luteal phase (the time between ovulation and your next period, which varies less than the first half of the cycle).
Track more than one number
The Nawah app saves all of this automatically — week, weight, movements and contractions — in one place.
