@Ellenn Ah okay that makes sense. Fingers crossed their tests are accurate and you did ovulate like they say. Do you often have different cycle lengths each month? If they scan you on Saturday and you ovulated, they book the TF for Tues? And if you didn't, then what? Do they move the TF back a few days to wait? With a TF of a fresh, do they do that after the Day 5 blastocyst stage, so on Day 6, or do they transfer it on day 5 itself?
Ahhh okay! That make sense. Was the fluid accumulation seen post collection or before? My bloods, like yours, have been fine all week, so I think like you that isn't the deciding factor. But I imagine, having PCOS they are thinking the surge in hormones and OHSS symptoms will come on after that as that can, like you say have late onset, or go into OHSS right after. I don't know if it's based on clincs, or individual people. My clinic said that they once collected someone with 55 eggs, and didn't go into OHSS and they did the transfer and she is due in a few weeks! So I guess my clinic don't go off number of follicles, who knows.
Lining is still sat at 5.5mm. It hasn't gone up since that measurement on Saturday. I know that the estrogen surge post-trigger helps thicken it up, so maybe that's what they're relying on, and don't want to add in estrogen tablets now, incase that might tip me over the edge when I'm triggered, to go into ohss?
