Ummm me and my boyfreind went kinda out of control four days ago and I think he came on or near my vagina while we were standing.although he denies it I had a feeling he did.so I took postinor two after 26 hours and the second tablet 12 hours after the first.and now I'm having slight cramps lasting for about 3-4 seconds but I don't have my period.i am afraid and worried that I may be pregnant? So someone please advice me??
