Idk what to do

McKayla

My bf and I had sex on Wednesday and we had a mishap. The condom broke and he came in me. I took Plan B right after it happened (within the hour). I was suppose to get my period yesterday, but I'm a day late. I'm really worried but it's also been a day. I've read the side effects that it could make you bleed, spot, or miss your period. Should I be worried?
