Dominant follicle turned into cyst ? IUI #4

I went in today for my follicle scan prior to my 4th IUI and my only dominant follicle measures 3.2mm, which they’re considering a cyst . Unfortunately no other “dominant” follicles are on either ovary I had a few 1.5mm but nothing significant . I took 7.5mg of letrozole days 3-7 of my cycle and today is CD11. My LH was 11.98 and my estradiol was 205.81 . Just looking for anyone going through something similar . I had a 3+mm cyst on my right ovary last cycle but had other dominant follicles so we still did the IUI which failed and that cyst is no longer there . Thanks ❤️
