Too mature?

At my U/S the day I triggered, I had 4 follicles: 26.7, 16.3 left side and 27.0, 21.9 right side. IUI approx 24 hours later.

Any success stories with large follicles? All the PA said was if this cycle didn’t work (1st) that we would do the U/S cd11 instead of 12 - I assume that’s because the follicles could have been too mature.

I really hope this works. I doubt my husband would be up for another IUI. 😢.

Hx: 3 healthy pregnancies and births followed by 1 mmc and 1 chemical. I turn 40 in 2 months...
