Progesterone Medication

Elysia
Saw my P-nut today!!! He/she was facing forward so we couldnt see it's heart flickering but i am 6wks and 1 day but baby was measuring a week early about 5 weeks and 2 days. Which i believe becuz when my blood test came back on the day i was due for my prd, my hcg was only 1.5 and my progesterone was 14.5. So i may have just ovulated late last month. ❤️ mc in august with baby #1 so im praying this one sticks. Baby dust to everyone expecting!!! 
However i am technically high risk due to my progesterone dropping from 18 on dec. 8 and today it was down to 9.5...And my HCG was 5200.  Ive started Prometrium 200mg once a day today until 15 weeks when the placenta takes over. Has anyone had to take progesterone and have had a a full term and a secessful pregnancy? I would love some feedback from you ladies.
