What you know about birth control: Nearly half of all U.S. pregnancies are unintended; abstinence is the only sure-fire way to prevent pregnancy (and protect you from STDs); smoking while on the Pill may increase your risk of heart attack or stroke; as long as you are still getting a period, you can get pregnant during menopause. But here's something you may not know:
We think IUDs work best. They're not the most popular birth control option, but many experts think they should be: Intrauterine devices (IUDs) and implants are the most effective form of reversible contraception available and safe for most women, say recommendations from the American College of Obstetricians and Gynecologists.
IUDs are plastic, T-shaped devices doctors insert into the uterus that release either copper or hormones. The copper version prevents pregnancy for up to 10 years, the hormonal IUD works for about five -- both types mainly interfere with the sperm's ability to fertilize the egg or keep the fertilized egg from attaching to the uterus. The hormonal one also thickens cervical mucus and thins the uterus lining. Contraceptive implants are matchstick-sized rods that are inserted under the skin of your arm and release ovulation-suppressing hormones for up to three years.
IUDs and implants can cause side effects, such as cramping, irregular bleeding, or headaches. But complications are rare, side effects lessen or disappear over time, and failure rates are much lower than with the Pill or condoms. Talk to your doctor to see if an IUD is right for you.
