Contemplating plan b

Kaydee

So my bf and I had sex. He pulled out early and said he is 99% sure he came after he had pulled out. There was a lot in the condom and it looked like some might have gotten on me. However we are not sure if it was his or mine (I didn’t come tho) I took plan b about 2 1/2 weeks ago. And had my period and was fine. But i don’t know if I should take it again. Any thoughts???
