Using Clomid 100mg

I've been on Clomid for 2 months now. The first round was unsuccessful at 50mg so my OBGYN put me on 100mg this month. This month I ovulated and last month I did not. This month I've also been experiencing ovarian pain in my right ovary. What could this mean? I also have enlarged breasts and swollen/very tender nipples but no discoloration. Has anyone else had these symptoms with Clomid? Any help is appreciated.
