SUZANNE LaJOIE, MD: When a woman ovulates after delivery is variable. In women who are nursing, lots of times ovulation is suspended for a while. A woman who is not nursing may ovulate, actually, six weeks after delivery. When women are breast-feeding, they're not as fertile. And, a lot of times, women will not get a period when they are nursing.
ANNOUNCER: But that doesn't guarantee they won't get pregnant.
SUZANNE LaJOIE, MD: My recommendation is that women don't rely on that for contraception, especially if they feel strongly that they want to hold off on getting pregnant again.
ANNOUNCER: The choices that couples have for contraception after childbirth fall into four categories: hormonal methods, barrier methods, sterilization, and natural methods.
SUZANNE LaJOIE, MD: In terms of hormonal methods of contraception, there are birth control pills, there are birth control patches, there are vaginal rings and there are injectables that can be used. There's also an IUD that has a hormone in it as well.
ANNOUNCER: But hormonal choices have to be made carefully.
SUZANNE LaJOIE, MD: If a woman is breast-feeding, I won't put her on a method that contains estrogen. I'll use either a progesterone-only pill, a progesterone-only injectable or an IUD.
ANNOUNCER: Certainly, of all the hormonal methods, birth control pills have been the most popular, particularly in women under the age of 35.
SUZANNE LaJOIE, MD: Lots of women use birth control pills before they get pregnant. It's something that they're familiar with, it's easy to use, and it's effective.
