IUI Sun/Mon, but have thin uterine lining


I am doing my first <a href="https://glowing.com/glow-fertility-program">IUI</a> on Sun & Mon. I was on Clomid CD3-8. Went to 1st u/s and measured 3 follicles (21,20,16), but needed to redo u/s due to thin uterine lining (from Clomid). Did 2nd u/s and have 4 huge follicles (22,21,19,15) that are ready, plus sonographer saw little follicles as well, in addition to the 4; At risk for multiples, but I would love to have twins tho 😍 We are unsure whether to continue with <a href="https://glowing.com/glow-fertility-program">IUI</a> due to uterine lining being only 5.7 thick... they left it up to us...so we decided to give it a try... therefore i will be triggering tonight with Ovidrel, <a href="https://glowing.com/glow-fertility-program">IUI</a> tomorrow and Monday morning. I am worried my uterine lining is too thin. Anyone get a BFP with these circumstances???
