Sub chronic hematoma

Yes I know that I’m overthinking but I still can’t stop I’m panicking because I’m not bleeding. Dumb I know but when I was bleeding the bleed inside was getting bigger on scans and I havnt bled in almost a month but I’m scared incase it’s still getting bigger but faster coz it’s not like coming out and ik it can also be reabsorbed but that wasn’t happening before and the doctors were worried about baby having space to grow when I’m further on at the last appointment because of the size of the bleed. I have a scan a week on Monday but I can’t stop overthinking. My belly feels huge and I’m scared incase it’s just blood. I have been told I’m at higher risk of miscarrying because of it and I’m terrified incase they’re gonna tell me I’ve had a missed one at this next appointment They genuinely didn’t seem very hopeful for the pregnancy
