I want to see ER last night thinking I was going through a miscarriage due to bleeding and blood clots.

They did blood work and a transvaginal ultrasound, when the doctor got the results back she came in and told me that I'm having twins and that there was still a possibility of me miscarrying them. I please ask for prayers for a healthy pregnancy. I just want to know if my HCG levels are fine. I'm still not sure how many weeks I am but according to my lmp I'm about 6 weeks pregnant. I go back in 2 weeks for an update.
