Would anybody know if this black chunck is part of the sack because my pregnancy would’ve been 9 1/2 weeks but the sack was reading 5.6 weeks two weeks ago the fetal pole lost its heartbeat so for two weeks there was no heartbeat and then bleeding started on Tuesday Wednesday got very heavy yesterday and this was more today lot of clotting but this was the biggest clot so I was just wondering if anybody knows if that’s part of my insides of the sack
