I've been having sex with my boyfriend for quite a while now and we had protected sex on the 28th which was one of my most fertile days. However,the condom broke.He did not cum inside me though. I have been actively exercising a lot lately and also been stressing all month about getting my period. My period was due on the 16th april and I still haven't got it. I tried doing the sugar home pregnancy test and that came out to be negative. I'm pretty stressed because the last irregular period I had was in january. Is my period late because of stress/excessive exercise or could I be pregnant?
