Birth Control Basics for Moms

It might be hard to believe—especially if you're seven months pregnant with what feels like quintuplets, caring for a colicky infant, or just feeling about as desirable as sack of potatoes—but someday you're going to want to have sex again, which means now is a good time to start thinking about what method of birth control you'll want to use. Maybe your old method will work just fine, or perhaps you plan on nursing and want to try something hormone-free. Thankfully it seems a new birth control product hits the market each year (although we're still waiting on a pill for the guys!), so moms have more choices today than ever before.

The birth control pill is a very popular choice for contraception among women and is considered to be 99-percent effective when taken properly.

If you are nursing, your OB-GYN will recommend a progesterone-only pill (or mini pill) because this hormone won't interfere with your breast milk production or quality (the pills that contain a combination of progesterone and estrogen can decrease milk production and pass through the breast milk to your infant). When taken as directed, the mini pill is 97-percent effective.
