I am freaking a bit, I have a belly that sticks out about two to three inches past my C cup breasts from my eyes' vantage point, I am still getting what appears to be a normal period, I am feeling plenty of movement in my belly, it seems like my body is sending my brain alarms to notify it that it is pregnant, but I tested negative on pregnancy tests (one at the doctor, and one cheap at-home test). Is there any chance that I may be pregnant? I am a tobacco smoker and I am on medication for bipolar disorder. Please help me.
