Sex and the pill

Kenzie

So I had some trouble with insurance and had to go off my birth control for a week. I got a new pack Friday, but Friday night I had unprotected sex. He didn’t finish until after he pulled out and I took a Plan B the next day, around 12 hours after. I’m about 230lbs so idk if that makes any difference on the Plan B

I bought 2 pregnancy tests to take in a few weeks, but what are my chances of pregnancy?
