So I had a blood clot and bad cramps on the 12th May. A friend of mine said her miscarriage went like this and I showed her the pic. She said It looked like how hers was. Went to a sex clinic on the 14th today. Took a test and it said negative. Is there a chance it could have been a chemical miscarriage. I read hgc levels can decrease or something 2 days later. Had a strand of tissue yesterday as well
