I had kind of a weird response to Clomid. I ovulate naturally but Clomid made me not ovulate -- I started to develop 2-3 follies and then they stopped growing before maturity and my estrogen wasn't rising. That was after 5 days of 100mg. My RE had me take 5 more days of 100mg and come back in a week, and I finally had a mature follie so we could proceed with IUI -- but only one. At that point I was just happy to be ovulating and that the cycle wasn't a total wash. It did not result in a pregnancy, though, and we moved on to IVF after that because I didn't want to do injects IUIs and Clomid and I were clearly not a good match.
On the other hand I had a good response to Follistim during my IVF cycle, with 22 eggs retrieved and a high fert rate. So I don't know your entire history but I don't think your response to Clomid necessarily means you have an egg quality issue.
