I began to miscarry on August 19th. I had heavy bleeding with large clots for about 2 weeks. I have been spotting and light bleeding ever since then. Today I started bleeding quite heavily and was lucky I was wearing a skirt at school otherwise I would have had to go home and change...I passed 2 medium sized clots. Is this residual of the miscarriage or is it my period? I went to my OB on September 1st. I was still bleeding, but not heavily and he did an ultrasound to see if I passed everything. I did, according to him.
