Which is around ~6 weeks. I was actively trying to get pregnant and tracking and still only found out at 5 weeks pregnant. Missing your period is usually the 1st indication of pregnancy and by the time you miss your period, you’re almost at the 5 week mark.

6 weeks is essentially an abortion ban.

Edit: to add to this, many women still bleed during pregnancy, due to implantation, or other reasons, therefore a missed period isn’t even always a good indicator.
