I had my first blood draw at 5 weeks, my HCG level was at 751. I had another two days later at 5w2d. The second one went up to 1085, but obviously didn't double. I've had a miscarriage before and I was wondering if anyone had something like this happen and have a successful pregnancy? I'm freaking out so any advice/insight is welcome. Thank you!

UPDATE- at the ER now, 3rd HCG levels were at 1750, not doubling but on track to double at 69hours. Hoping for the best, waiting for ultrasound now.

FINAL UPDATE- ultrasound showed an empty sac in the uterus, normal for it to be empty this early. Just thankful it's in the right place. Now I just have to wait I guess..
