If you are having regular periods then your ovulation should be regular too.
I used to find that sometimes I had more ovulation pain one cycle and the next wasn't so bad. In fact the cycle when Caleb was conceived was particularly bad with crampy pains lasting for 4 days. I was convinced I might have released more than one egg!

Are you getting EWCM along with the pains? If so then this is a great sign!

I've never heard of giving hormones to bring on periods and stop growing. I hope someone here can help you with that part of your question.
Good luck!
