I had a child in December of 2010. My last period was around August 28, 2011. I have taken 6 pregnancy tests between late September and this month. They all say that I am not pregnant. Is it possible for the test to be wrong? I do not, and did not with my first, have typical pregnancy symptoms. The only I could think to have is food cravings, sleepiness and indigestion. Lately, I have been feeling small movements but they could honestly be normal stomach movements. I don't have health insurance and so I'm trying to figure out if I should go to the doctor or not. What, if not pregnancy, could cause me to miss 3 periods in a row? I do not have extra stress or other factors that could change my cycle.
