I unfortunately got a BFN with this last cycle, but in going over everything with my RE he said my E2 levels were low during my luteal phase (checked on 10+12 dpo). My P4 levels looked great, though. For my next cycle he’s recommending I supplement with an estrogen patch after transfer.
What role does E2 play after transfer and does it effect implantation potential? I’m with a new clinic/RE and this was the first time I had luteal b/w done.
