What is Heather?

Heather (norethindrone) is a birth control pill. It keeps you from getting pregnant primarily by thickening the cervical mucus at the entrance to the uterus so that sperm can't get through. It also creates hormonal changes that make the uterus and the tubes that connect the ovaries to the uterus inhospitable to sperm and may prevent ovulation (release of an egg). Heather is sometimes called a "minipill" or POP (progestin-only pill) because unlike most oral contraceptives, it contains only the hormone progestin, not estrogen as well. If you take it as directed, Heather is more than 99% effective.
