Hi!
If you were my patient, I would advise you to stay off of birth control if you are actively trying to conceive. Give your body a few months to establish a regular cycle and then you can know better how to time intercourse with ovulation. Check out our menstrual cycle and ovulation trackers under the "Health Tools" tab this site. In the mean time, if you have intercourse approx every other day, you might get lucky enough to forget about all of the record keeping.
Good luck!

also I don't understand how ovulation works do I ovulate every month? or is it possible for women to skip a month without ovulating.
