I agree....I just wanted to add that sometimes it takes a while for your body to regulate. It took me a good year and my cycles still weren't exact before I got pregnant. I was on the pill since I was 15 and stopped when I was 24. If you track your cycles..then you'll really get to know your body well. I noticed that I would get acne around the time of ovulation. I also paid attention to my cervical mucous and I was lucky enough to feel ovulation pains so I would have an idea. Good luck....don't get too frustrated if you don't get pregnant right away.
It can take some time for your body to regulate itself after being on the pill. On average, a woman ovulates 14 days BEFORE her period, but that is with a 28 day cycle, yours can be different. The best way to know is to track your cycle for a few months and you should be able to figure it out. Good luck to you!
