Good luck to you and i am sure that the flu shouldn't mess it iui people get sick all the time.
I have had the worse cramping like feeling since and before my IUI that took place on Tuesday. I feel bloated and just off. This is my 2nd IUI as well and the doctor said he felt confident it would work BUT now i have the flu so I am hoping that does not screw it up for me
I wish you the best of luch
