Okay, so I'm on birth control, I take a pill every afternoon. I had sex with my boyfriend and he came inside me because he knows I'm on birth control and didn't think anything of it. But, afterwards he started to freak out and wanted me to take Plan B, so I did. The reason I justified taking it, because I know you're protected with birth control, is because I was only about 2 days into my new pack and I just wasn't exactly sure how all that worked. I'm on the week of my sugar pills now, and I should've started my period yesterday, as it was a Sunday. So, is my period just delayed because of the excess hormones? Or, is there a chance I could be pregnant? Should I continue on with my new pack even if I don't start my period at all this month?
