Day 5 post IUI

KYAS

I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> last Wednesday with a 30mm follicle. I have three questions. 1. First is the size of a follicle sometimes to big? 2. I have been having on and off cramps/twinges on my left side in front and my lower back is that normal this many days after? 3. I am on progesterone can it be a side affect of that?. Anyone’s help and experience would be amazing.
