Iui-if you've had one please help

Trying to decide if it's worth it. Me and my husband have unexplained fertility ....been trying 2.5 years. Just finished my 3rd round of clomid and I'm done trying for a month or even a few. But I want to know, did it work for you, what tests did you have to do, what medication were you put on, how many visits? Or anything at all that would be helpful so I can decide if I want to move forward with that or not. Insurance doesn't cover a penny, so I would really love any info, advice, whatever! I'm grasping at straws now
