Progesterone drop, hcg rise 5 weeks plus 3 days - any ideas?

[singleswimmer]

Hey everyone, so my low starting hcg has continued to double appropriately, but my progesterone level dropped a lot and Im trying to make sense of it - I had a fresh IVF blastocyst transfer with initially sky-high progesterone, have been on cyclogest 400mg three times a day, and and my Danish clinic advises to stop cyclogest 14 days after transfer and let the body take over. I didn’t realise this until this week and I felt uncomfortable about stopping so I continued on it but twice a day instead of 3 times a day. It dropped a lot from 120 4 days ago (15 days post transfer) to 23nmol/L yesterday - v v low! - when my hcg was 685. My hcg is 1000 today and there’s a gestational sac on ultrasound so it’s not an ectopic pregnancy, and I’m assuming it’s going to be an early miscarriage but just can’t quite make sense of the progesterone drop combined with rising hcg. Does anyone have any advice?

TIA! 🤗🤗🤗
