We did a total of 6 cycles of Clomid with IUI. The last 2 cycles I also used Ovidril. We needed to do IUI's because my OH has very low sperm count, very low motility rate, and a pretty high abnormality rate. :/ We didn't do 6 cycles in a row, we took a month or 2 break in between some cycles. I started with 50mg of Clomid, and found that when I took it for 2 continuous cycles, I released 2 mature eggs on the second cycle (I have no problems ovulating on my own). I think I took Chlomid on days 2-7. I can't be sure anymore. For our last IUI my OB upped my Chlomid dose to 100mg, (I had also done back to back cycles this time) and I released three mature eggs. He told me the chances of all three taking were pretty slim and to expect twins if I still decided to go through with the IUI. I decided to do just that, and ended up with triplets! LOL 2 identical, and 1 fraternal.
As far as side effects, with Chlomid I was super sensitive and emotional! I cried about EVERYTHING! LOL The worst part was that I KNEW I had no reason to be crying, but I couldn't stop myself! LOL It was pretty crazy. And it never mattered what time of day I took them.
As far as Ovidril, my fist cycle taking it, I reacted pretty badly. I had severe nausea, diarhea, and extremely severe cramping. I also broke out in a bad rash all over my body. I won't lie, it was pretty bad. I was really upset about the whole thing, and didn't think I would agree to take it again. But the second time I took it, I didn't have any reaction to it at all. I guess my body just had to get used to the new drugs.
Lots of luck to you!
