Just had my 5th iui today, it wasn't very painful at all, I was worried... The re said I only had one follicle... That is why it was not painful..
I can related to it hurting when you walk.. . It feels like something is inside of you that is going to pop!!! Like gas pressure (not so much the farting kind ha ha) just pressure. My re says it is a good sign, and I can tell them which ovary has the follicle(s), before they do the iui!!! The side the follicle is in, is the side it hurts on. Let me know how you are doing and if it works for you... Good luck to you and all of us!!!
