As I was replying about my being maxed out on progesterone support for the last few 2ww's due to prior big drops in P4 at other times in the past I began to wonder, can too much progesterone support prevent implantation?

I am wondering about this because I am pretty sure that with this DE cycle they are going to have me on the same amount of P4 support which is 400mg supps 2 x day and 2cc's of PIO daily. I am feeling not so optomistic about my upcoming DE cycle( started the Lupron yesterday) just based on my history of so many OE failures and the knowledge that first time DE transfers are not always successful.

I would hate to be on high doses of P4 if it could adversely impact a young healthy DE? Any thoughts on this, or is the current thinking that one can never have too much P4? Thanks ladies.

I took pills, twice weekly PIO depot shots and used Crinone every night. Didn't go off until week 14, 2 weeks ago.
