We count a user as pregnant if all of the following requirements are met:
The user has switched to pregnancy mode in the Ava Fertility app. (This ensures that we are only counting users who specifically tell the app that they are pregnant.
We do not count users as pregnant who simply don't enter a menstrual period for an extended length of time, for example.
The user has stayed in pregnancy mode in the Ava Fertility app for at least 30 days. (This ensures that we are not counting users who switched to pregnancy mode out of curiosity to explore this mode.)
The user was actively using Ava Fertility in the two months leading up to her pregnancy. (This is an additional safety guard to ensure that we are not counting any users who may have stopped using Ava Fertility before becoming pregnant.)
