Answer Box: After having my son, I went on birth control for a year. I then stopped it two years ago while ttc. 4 months ago I had a miscarriage and now I haven't had a period for going on two months. I have heartburn, really bad cramps and sometimes my boobs are sore. I have taken 2 pregnancy tests two weeks ago. Both were negative. I'm not sure if I could be pregnant and it not show up or what's going on. Can anyone help answer this for me?
