Just looking for thoughts/past experiences. May 2017 I had a d and c done due to a blighted ovum. Found out August 3 that I am pregnant again. Visited with dr last week and set up ultrasound for Monday, the 14th, which according to my last period I would be 7w and a day or 2. U/s looked good but was measuring between 5-6 weeks and saw a yolk sac. Which we were so happy to see considering we didn't see a thing last time. They did blood work right after that and hcg levels were 17,000. Hcg levels from Wednesday only went up to 18,500. Im so worried because I thought they should be doubling every 48 hours. I don't want to go through miscarriage again! Please pray!
