IUI and sex

sara

I'm cycle day 10 and I had 4 follicles today (16mm, 15, 12 and a few 10's). This is the first time we are doing <a href="https://glowing.com/glow-fertility-program">IUI</a> and idk when we should have sex. I go back Saturday for a ultrasound to check the size but they will most likely have me trigger that night. So should we have sex Thursday, Friday, Sunday and Monday. I just don't know. <a href="https://glowing.com/glow-fertility-program">IUI</a> will be Monday most likely
