Dianne, don't feel blue! This is gonna freak you out, but it looks like we have similar experiences! You know, when I had my CD12 ultrasound, my biggest follie was only 18mm and my lining 5.4mm, which is thin. But my lovely RE assured me that both my lining and follies will grow, which they did when I did my CD15 ultrasound!
So don't be sad, I was really feeling down on CD12 too, but there's really still hope!! Will you be going back for another ultrasound on CD15?
Stay positive!!
