Hey ladies. I have a progesterone deficiency. I was put on Prometrium to help with development. My first two ultrasounds were great. 146 for a heart rate the second time. I am coming up on my 11 week scan. I am so scared something has happened. I lost my little boy last May at 10 weeks due to Trisomy 21. How likely is it for next one to have this as well or should I relax? I want this baby more than anything. We have lost 8 in total with one live birth 10 years ago.
