I had a tummy tuck in 2004 so my stomach is very flat. I was pregnant in September, found out in october that i had lost the baby between 8-10 weeks. I wouldn't bleed so I had a D& C on October 17 my stomach went flat a few days later, about 2 weeks ago my stomach popped up again, and its getting bigger and very hard im exercising and dieting. Nothing is phasing it it is getting worse not better! I have had no period, I took a pregnancy test on thanksgiving and several days prior as well and they were all negative I 'm really desperate and depressed.. please help
