Gals, dun hv to worry too much on lining thickness as long as u hit 8mm though ideal lining is 10-12mm. My first pregnancy, during last scan before ER was 14mm, I asked dr Kelly loi, the ivf consultant then if too thick lining will hinder success. Coz at ET, it shld be >14mm. She said not so for the ivf cases. Well, true enough, FYI, I bfp.
My 2nd n 3rd pregnancies, my lining was 12mm at last scan. ET was another 3-4 days after right? So, my lining will be thicker then right. I bfp again both times coz my thicker lining was not caused by endo. I will always ask dr loh how was my lining at ET, he always said lining was good. He has nv tell me too thick!
So, there is no such thing as too thick lining is no gd.. Or wat others claim so.. Some just assume they fail coz lining was too thick.. Of course if thick lining is caused by problems such as endo... Then, yes will affect success...
To be pregnant, is more thsn just lining thickness, n embyro quality. It is too complicated for human to analyses. Just Be positive & pray! U will carry your bundle of joy soon as long as u dun give up!
