Can you ovulate on birth control?

Depends on the BC: If you have a hormonal IUD, implant or take the pill properly you don't. If you have a copper IUD, use condoms or miss enough doses of the pill you likely do.

You probably dont: The primary method for a birth control pill is to keep you from ovulating. More than 90% of those on a pill will not ovulate.

Birth control: The whole idea of birth control is to prevent ovulation. If you skip some days then certainly you can ovulate.

Yes, but: If used properly it'll only be around 2% of the time.
