? for ghost or anyone, Implantation not happening

[kez01]

hi all,

thanks for all the info its really helpful. I dont have my appointment with my doctor until september 12th which is a really long time and I'm really disappointed I have to wait so long.

Ny4th try; I'm sure your eggs are not too old, and I'm keeping my fingers crossed for you, this is your lucky time, I'm sure one of those little embryos will stick. Keep your chin up.

Ghost or IVF nurse, is there a way to tell when your receptivity is at its best. I want a natural FET cycle but I dont always ovulate, would this make a difference to the receptivity of the endometrium. Also I have noticed people in the US tend to do progesterone shots and some also have oestrogen patches. We do the prog pessaries, are the shots better and would you recommend the oestrogen patches or, would the patches affect my endometrium.
Sorry for lots of questions. I really do want to be informed when I see my doctor.
Thanks

There is no practical way to tell if the endometrium is receptive at the proper time, unless of course implantation occurs. Endometrial thickness is not the same thing as receptivity. There are various researchers looking for biochemical markers of receptivity. The problem may arise that receptivity is supposed to occur after embryo transfer any way, so if it fails to occur, it's already too late.

The good news is that, in FET (and donor) cycles, the endometrium is almost always receptive (90% or better). We know that because we can get initial pregnancy rates that high. The remaining 10% might also be receptive for all we know. A failure to implant might be due to embryos or endometrium (or both).
