Day 10 US with 14.6 follicle on left and 16.2 on right with my lining only at 6.3

Hey ladies.

I am doing my first IUI (hopefully) and got my day 10 ultrasound this morning.

I had one follicle on each side with my left measuring at 14.6 and my right at 16.2...

But my uterine lining is thin and I only have my left Fallopian tube.

I am nervous my left follicle will not grow and that my lining will not thicken and iui will he cancelled.

If anyone has any experience with this situation I would love to hear about it!

Or just any hope that anyone has to shed❤️
