I had a miscarriage end of October. Found out I was pregnant last Wednesday. My doctor wanted to check my hcg levels this week to see if they're rising appropriately.. Last pregnancy never got up past 32... Just got the call for my results of this pregnancy and I am ecstatic. Monday betas were 655, and yesterday they were 1851. They've almost tripled in 48 hours. And I get to go in next Friday for an early ultrasound to check for dating.
