Lining for IVF

am

Soooooo I went for my lining check for our upcoming <a href="https://glowing.com/glow-fertility-program">IVF</a>. It was 8.75 I am suppose to start the PIO shots in 2 days and the nurse told me that once I start the progesterone shots that the lining pretty much stops growing. I guess what I’m asking is 8.75 good for a blastocyst transfer?? Anyone that’s been through a transfer feel free to share experiences. It’s our first so this is all new to me 🤦🏻‍♀️
