Hi, I am a 34 year old mother of two, I have been having cramps for like 2.5 weeks...I don't remember when I started my period last month, but I know that I have not started in Feb. and there is only 1 day left in the month! I took a home pregnancy test about 1 week ago, and it was negative! I don't understan why I am cramping and having signs of pms and not starting! If I am possibly pregnant, why negative test..could it have been too early to test?
