Has anyone else had a chemical miscarriage? I think I possibly could have had one and would like to hear from you guys... I had two very large blood clots today. They were both pink, dark red, and had a dark blue line through them. larger than a quarter. I had cramping 2 days before today, but I just passed it as bad period cramps. I took over the counter pain pills. my "period" is a week and a half early and I just started birth control. only took 3 pills then I started. this has never happened to me before. my husband and I have been trying for 2 in a half years now to get pregnant, and I started bc to help with my ovulation... I just want advice from you guys please
