Bleeding

So on Thursday(6/27) I went to the bathroom and when I wiped I had blood all over the toilet paper. I was like what the heck so after 45 I started having cramps and still bleeding. I went to urgent care knowing I was having a miscarriage. I get the ultrasound and the tech was telling me she couldn’t say anything to me. I said “it’s ok I already prepared myself” she tells me “I can’t show you the screen” then proceeded to move the screen so I could see. There was a baby with a heartbeat and just moving around. I was so relieved. I measured 7w4d 3 days farther. The dr came in and told me I had a small subchronic hematoma. Had anyone experienced this?
