Needles and u/s rods

Abc
After weeks of back to back blood work drawings, lab result calls from the doctors and multiple transvaginal ultrasounds every week, I got a call from the doctor today telling me that my HCG isn't doubling like it should. I'm going back in on Friday morning for more blood work and another ultrasound and really need the positive vibes and prayers from anyone that is able! Please pray that my HCG will double or triple for Friday's tests, it was amazing to see and hear the baby's heartbeat yesterday, the little peanut means the world to me. Please help! Love Ashlee
