Pregnancy Info HOME

Hi, I was sure I was pregnant and I had what I thought was implementation bleeding. However, preg tests always said negative and low and behold I had my period just over a week late. I then started to use the pill (I had used it in the past and stopped) but my symptoms of pregnancy seemed to multiply. I put weight on in my lower abdomen. I had a small withdrawl bleed but I was so convinved that I had an ultrasound done and what would have been 9 weeks pregnant. It showed no sign of a pregnancy whatsoever and my uterus lining was thin as would be expected on the pill. 4 weeks later I am still putting on weight in my lower abdomen and I feel very pregnant. It's not so much weight but a hard muscular wall that makes all sorts of noises when prodded. I am not conspitated. Is it still possible I am pregnant? Please help
