Ok, so I don't know if this really means anything, but I really am a little worried. I have pretty normal periods. My cycle is usually 26 to 31 days long with my actual period lasting between 4-6 days. And they are heavy. I also have alot of clots and cramping. I have been monitoring my periods for a year now because I hate having them surprise me. Anyway, my last normal period was on Feb. 18, 2010. There was absolutely nothing strange about it. My husband and I had sex on the 3, and I only remember this because I happened to notice it was right next to my ovulation, which was supposedly on the 4 of March (I don't really track that, the calendar I use does it automatically). Anyway, back on track. I expected my period to come on the 18 of March. Well, about 2- 2.5 weeks ago, I started to feel really tired and sick and my breast were really sore. I thought it was just period symptoms, although they don't usually start that early. Then on the 12 I started bleeding. This was alot earlier then my normal periods and was really light. I don't know how else to describe it, but it was not anything like my normal period. I took a pregnancy test, 3 of them actually, but they were all neg. Should I wait a little bit and take another or just wait to see if my next period comes? Has this ever happened to anyone else?
