and my lining went to 8.1mm!!! My RE did the sono herself and it was really interesting that she would move the probe slightly and it was 7.5mm and then it went to 9.6mm which was strange. She said she was going to go with the 8.1mm and I started PIO last night and our transfer is scheduled for Monday!!!!!!!! My lining was not trilaminar like she hoped for but based on my sono from my last FET it didnt seem to be trilaminar then either. There is debate on whether it actually matters but we shall see if it does by me getting pregnant or not. I am so happy to get this FET on the road and hopefully in less than 2 weeks I will be 4 weeks pregnant lol. I have hope and faith that this FET will bring our rainbow baby!!!
