I havent got a period since December 1st 2006. I am today 3 months late. I have taken 5 home pregnancy test from the store all have come back neg. I am 22 years old if this helps out as well. I have had a baby in the past and had some problems with pregnancy then my baby came 1 month early and was a low birth weight baby. What I want to know is if I could be pregnant and these home pregnancy test could be wrong. I have heard from others that sometimes these test can go wrong. So far I am having really sore boobs at night and I am getting alot of heartburn when I eat or lay down. I also am getting cramps like my period. I also am having clear discharge on my panties. I am also getting alot of headaches. I have not been to the doctor yet but I am thinking maybe its time for me to go in for a check up. I just need some advice from someone if i could be pregnant or not. I hope someone out there can help me.
