How long does it take to first ovulate after i stop taking the pill?

2 weeks to 3 months: Most women ovulate soon after stopping the pill. Pills reduce fsh from the pituitary, limiting ovulation. After stopping pills, the pituitary gradually recovers. Some women ovulate within 2 weeks, others require 3 months or more. Women can try to conceive immediately after stopping the pill. If periods do not resume within 3 months, ask your doctor for advice.

Pill: Usually one to three menstrual cycles prior to the use of the pill. So if you menstruated before every 30 days, then 1-3 months.
