Due to prior miscarriages I've been monitoring my HCG & progesterone very closely. On Sept 11th we got our BFP! On Sept 12th my HCG was 116 & my progesterone was 10.9 (both on the low end of normal). I started progesterone suppositories right away. On Sept 15th my HCG was 495.6! Perfect!(5w+1) On Sept 16th my HCG was 755 & Progesterone was 21.5! (5w+2) Everything is looking good! September 20th HCG is 2423! (5w+6) Awesome! September 27th HCG is only 5809. (6w+6). Not good. September 28th I go in for an ultrasound. They see Gestational Sac & Yolk sac, no fetal pole. I have a tilted uterus, so I know sometimes that makes it hard to see on an ultrasound. The Gestational sac measured 5w+6, I was supposed to be 7 weeks. Not a huge difference. I haven't had any signs of miscarriage, no excessive cramping, no bleeding. The only reason for concern is the bad HCG level on the 27th. I had my HCG checked again this morning, just waiting for the results. But as we all know the waiting game is the hardest part. So I guess I'm just needing some encouragement. Anyone been through something similar?
