my boy friend and I have been trying to get pregnant for about 2 months now...I take a HPT every two weeks just to see but its always negative. I had a regular period and then just 2 1/2 weeks later I had another one but it was irregular...I mean early first of all and heavy but only lasted 5 days when it usually lasts 7. I also have sore breast and hot flashes. I am a mother of a 4 year old but no pregnancy is the same, so its hard to tell. What do you think? Can I be pregnant?
