When will
you get
pregnant?

Most fertility estimates ignore either contraceptive history or age. This tool takes both into account to provide you a personalized, research-backed estimate of when you might expect to conceive.

01

Enter your details

Your age, whether you've been pregnant before, your contraceptive method, if you're tracking ovulation, and how long it's been since you stopped.

02

Set an optional target date

If you have a specific conception timeline in mind.

03

Get your estimate

Per-cycle probability, and 6- and 12-cycle cumulative chance of conception.

Why this tool

Built on real data

Powered by two large prospective cohort studies (N=17,954 and N=2,962), not just general fertility statistics.

Accounts for your birth control

Return to fertility time is birth control dependent. Depo-Provera users have, on average, an 8-cycle delay, while copper IUD users have just 2. Method consideration matters for an accurate prediction.

Adjusts for your age

Fertility declines with age. Accurate fertility predictions take your age into consideration.
