I'm new to this but not ivf. I've done seven cycles of my own and now am on my 4th blastocyst transfer from an egg donor cycle.
I was aready on 3 Endometrin a day
- At 4w 2d hcg 250 and p4 22.8
We then doubled Endometrin to 6 a day.
- At 4w 5d hcg 1224 and p4 25.8
My doctor was surprised that my progesterone hadn't come up more.
I'm now back on the original 3 a day and have also added a 400 dose in the morning and night rectally (not as gross as you'd think!)
More bloods on Tuesday.
Would love to hear from anyone who's had low levels initially that have come up?
