I am having brown discharge for alomost a week now. When I was about 7 weeks pregnant I had gotten a sono at my local clinic. Thats where they determined me being pregnant. Well they could not find a heartbeat nor embryo, only a sac. and they told me that I had an abnormal pregnancy. I then had two options...get and abortion or let your body dispose of the miscarriage naturally. Well its been three weeks and I have had cramps that come and go and brown discharge and looks like small clumps off tissue? I am goin to my dr tomorrow.But I still have my food cravings, gainin weight and full breasts? Is that from the sac etc. and my hormones tellin my body im pregnant. OR is there anyways they could have been wrong and I am really pregnant?? HELP!!
