Abortion, plan b and precum

Hello everyone,

I was on birth control for two months because of my abortion but I never had any bleeding so that was freaking me out so I stopped using it. Now 19 days post pills I had unprotected sex but my boyfriend pull out close before he c** and I took a plan B within an hour after.

The thing is I’m not sure if I ovulated or not and that’s freaking me out because I know plan b wont if I’m ovulating.

What’re the chances I could be pregnant from precum and my ovulation delaying because of hormone disruption from pregnancy, abortion and birth control. I’m s cared I’ll be pregnant and have to do another abortion😭 please keep in mind before the birth control I never had any bleeding after the abortion
