is this my subchorionic hemorrhage?

Justice • son born 12-9-16👦 missed miscarriage 7-12-17 at 10 weeks👼 blighted ovum 2-5-18👼baby girl born 11-25-18👧

is thr black blob next to the gestational sac the hemorrhage? if so is it pretty big? my doctor said she would talk to me about it at my appointment on Thursday. this pregnancy occured straight after a miscarriage without a period in between. im scared this will result in another miscarriage because it looks big. its on the left of the baby. this was 7 weeks 3 days.
