Taken several pregnancy tests and i am not pregnant, my period completely skipped last month. I don't recall being under stress or anything i mean i had a few bills i was wondering how i was going to pay but thats about it. Still no AF its going on 3 and a half weeks late. My last 2 pregnancies i had a BFP after 1 day of my missed AF i know for a fact i am not pregnant. But where could my period have gone? I'm so stressed out over this situation. Has this happened to anyone else?
