I saw my regular doctor today, took another ultrasound and I saw the hearbeat. My doctor didn't seem worried, even after he found out I'd been to the emergency room when he was on call. Oh well. He told me and showed me the area that was probably the cause of the bleeding. He said it was a hematoma. With a google search it's basically a bruise. How I got it I dunno. If I'd known what it was I might have asked but he said it should be absorbed.
I feel alot better after having talked to my doctor. I have my normal check up on the 19th so that's good good too.
