Hemorrhage:(

Destiny

So I went to the er for pain in my left side it was sharp and hurt to walk, they checked my hcg which are at 124,000, I am 7wks 4 days according to ultrasound with a heartbeat however the dr said I have a subchorionic hemorrhage a small one and it could be a sign of a miscarriage and I am freaking out has anyone had this and had a safe pregnancy?
