Me and my bf had sex on Jul 23 and the condom broke. He said that he hadn't done anything yet. I was freaking out so I went and took the plan b one step pill 45 min after. I had just got off my period to. Yesterday night which would have been the 27th I was throwing up. Today the 28th I was bleeding a little bit. Would this be side effects from plan b or am I pregnate or could it just be my period??
