I think you might've taken it a bit late. Like you just BARELY missed the cutoff and the later you take it the less effective it'll be. Especially since you've ovulated, that plays a huge factor. And plan b won't hurt the baby because there is no baby to hurt. It stops the fertilization process. Sex ➡️ Fertilization ➡️ Baby. Just wait for your period, if you miss it take a test

Plan B is very effective no matter what your weight is. I took it last year when I ovulated and I didn't et pregnant. It will shed the lining of your uterus and you may bleed heavily during your next period but there is always that chance you'll get pregnant so make sure you don't take any medications that may hurt the baby until you're 100% sure.

I never heard of plan B not being effective on overweight women...but I know that you're supposed to take it working 72hrs of unprotected sex...so if you think you followed the instructions right than you should be fine

Plan b isn't abortion... It can't hurt the baby if the baby is already made. But it sounds like you took it too late. Especially if you think you have ovulated
