Hi there
I had a medicated IUI cycle with clomid 50mg, 1 follicle and pregnant 1st time, unfortunately I had a miscarriage at 10weeks but it does work and can work first time despite some really scary stats. I also take metformin as I have pcos and this is supposed to help the egg mature as well.
We will try again with another cycle in a couple of months as we aren't allowed straight after m/c but i really do wish you all the luck with your iui, really hope you get your BFP soon.
