Ovulated late on 25mg but then no ovulation on 50mg

Has anyone ovulated on a lower dose and then not at all on a higher dose? I ovulated day 21 with clomid last cycle but this time I didn't ovulate even on day 21 I had some pain day 32 so am doing another progesterone test next week to see if I ovulated then but even if I did it was very late in my clomid cycle and it will have taken longer than the other cycle?

Yes ovulated twice on 50 and not a thing on 100. It just gave me a 42 day cycle instead!

I ovulated on day 21 when using clomid and my fs said that if it didn't happen on cd 14 I actually ovulated on my own. Clomid didn't work for me.
