Hi, I had unprotected sex while ovulating. I thought I could be preg and had symptoms so I took a hpt a day before my expected period but it was negative (it would have been 12 days after conception). The next day I startd my period only Im having a much lighter flow than usual but I had really bad cramps the first day, a lil worse than usual but my stomach isnt really upset like it always is im actually kinda constapated (sorry tmi). But I was wondering if I could actually be preg or had a miscarrige.
