I believe I'm pregnant,I was very slack with my birth control pills (only had 18 in a 30 day period) and have regular unprotected sex with my partner a bit before my period was due I had some slight spotting, I also skip my period every 3 months(I know its bad!) So I continued to skip my period,I tried two pregnancy tests both negative,I have nausea,swollen sore breasts and mood swings.a few friends are saying I am,a few arnt. I was just wondering your verdict?

Also slightly lactating!
