:? I have the same problem,i was on birth control,and then after I got off for a while like 2 months later I became pregnant,and I had spotting,and then a blood clot,and then something like a period,nothing heavy though,and not that much pain,and now its gone away..So im wondering the same thing,i wonder if during a misscariage,you bleed heavy and bleed for a long time..Because I only was bleeding for 6 days..And during that time I had the one blood clot come out of me...I had a misscariage on christmas of "04"and I had a lot of clots come out of me,and I was bleeding heavily,..Keep meposted lol..Im having the same problem... :)
