My progesterone with this pg was below normal (though I forget the actual numbers) and at the start my hcg levels were on the low side too, though within the range. I clearly recall my dr saying when I was approx 4-5 weeks not to get too hopeful. Anyway, my hcg continued to rise, but my progesterone went up and down. I ended up having progesterone pessaries from about 6 weeks to 14 weeks. I do believe the progesterone pessaries saved my pregnancy - I had a lot of bleeding in the first 8-9 weeks, and it only stopped after I regularly started using the progesterone. The only "catch" is the expense - the more pessaries you can buy at any one time, the cheaper it is. I do know the compounding chemist needed 24-48 hours notice to get the progesterone in stock, but on one occasion they were able to give me several pessaries they had in stock, and I picked the rest up a couple of days later.

Has your dr recommended you have a scan? I had a scan at 5w6d to check what was happening. I had another around 8 weeks. The scans were comforting from the perspective of seeing a good heartbeat and bub's development.

Wishing you all the best, xx
