Dr. Q and ladies!!!! when did i ovulated

Iam in my third cycle of clomid. in my last 2 cycles i was under ultrasound supervision. Now my doc said it is not necessary. I took clomid from day 3-7, from day 8 i got colorless stretchy cm till day 11. from day 12 onwards iam extremely dry. All the two cycles i got my periods on 14 th day after ovulation. I want to know when did i ovulate. Iam on cd29 today. As per my calculation i should have got my periods on 30th of march. But i din get. so is there chances of ovulation even after the cm is gone dry.
