Irregular Cycles - Advice Please!

I'm 8 months off the pill & am getting very irregular cycles (Dr. doesn't think I'm ovulating). We tried 50mg of Clomid & I didn't get a positive ovulation test until Day 32 ? - anyone else have issues like this? Any tips on ways to improve irregular cycles?! Thanks in advance! ?
