Ovulation

Ekn

Guys just got of from my birth control pills last month and i did clear blue ovulation test. I ovulated on cycle day 17 and got my period on cycle day 33. This is why this month I start testing on cycle day 17 and now its cycle day 22 still negative . Is it possible that I stopped ovulating? Or ovulated early? I dont know my regular cycle couse only got my period naturally last month. Could you share your ideas about??
