Wahhh… my doc a bit fussy on lining thickness. He prefer above 8mm and the thickness is even. Last cycle certain part is thick n some is not although it was 8.3mm. In the end we decided to cancel the cycleThroughout my ivf journey, I don’t have a lining that has gone beyond 5.5mm and it was on max stimulation to get there. It seems like having a 6mm is good enough for most clinics. In my positive FET cycle, my last lining check before transfer was only 4.4mm.
