Hi. I expected my period to come 8 days from now (July 4) .. 3 days before my expected period (July 1) I had unprotected sex. I have a 32 days cycle. July 8 I took a pregnancy test and it came negative . But till now I don’t have my period. I am experiencing cramps and it’s like After a while it will go away then I will have cramps again. My breast also hurt. Didn’t have spotting.
