First IUI scheduled- questions!

I had a scan today with 3 decent follicles. 1 follicle was 20mm and two others were 15mm. I’m doing a trigger shot tonight and my <a href="https://glowing.com/glow-fertility-program">IUI</a> is scheduled on Monday! Excited and nervous!

We have <a href="https://glowing.com/glow-fertility-program">IVF</a> planned for next month so part of me wants this <a href="https://glowing.com/glow-fertility-program">IUI</a> to fail so I can do all of the embryo testing and maybe even choose the gender (we have a son and want a little girl this time). Is that insane of me to think like that? I’m 36 and husband is almost 46 so I’m paranoid about having an unhealthy embryo! Right now I’m just praying that God chooses the best path for us.

Also, I’m paranoid about twins. If I have two small follicles at 15mm, do you think it’s safe to say we won’t get twins and only the biggest follicle (20mm) will release an egg to be fertilized?
