My boyfriend and I BD a Lot my last ovulation and the day before I ovulated as well. AF was due yesterday, Monday the 20th and so far I've had nothing. I've had on and off cramping since I ovulated weeks ago and my boobs are just a little site today. I usually break out and have not gotten one zit and I'm not bloated either. I took a pregnancy test this morning and it was a BFN. Any ideas!?
