endometrium lining and iui


I have been in clomid for 10 days. I had my ultrasound today. my lead follicles were 21mm and some were 14mm. but my lining was at 14 mm. is that to thick? this will be my first time for <a href="https://glowing.com/glow-fertility-program">iui</a>. I'm trying to stay positive that it's going to work this time.
