Do I still need birth control?

Birth control is often something women, perhaps in their 40s or early 50s, stop worrying about a little too soon.

“We find that in most of the research, by the time a woman reaches the age of 55, she is 95 per cent likely to have gone through menopause,” says Mayo Clinic gynecologist Dr. Petra Casey. “Menopause is defined as one year of no periods. If you reach 11 ½ months of no periods, then have a period, the clock starts all over again and you’re still not in menopause.”

Wondering when you’re menopausal and can safely stop birth control? What birth control is best for women over age 35 or 40? Can you still get pregnant in your 40s and 50s? These are common questions.

Overall, almost half of all pregnancies and 75 per cent of pregnancies in women over 40 years of age are unplanned.

Also, some pregnancy complications and risk of miscarriage go up with age. So, if you don’t want to become pregnant, using effective birth control until you are truly menopausal is very important.

Depending on your medical history, your health care provider will talk with you about the best options for you. If you are at a healthy weight, don’t smoke, don’t have high blood pressure or history of blood clots, you can probably continue the oral contraceptive pill, patch or ring well into your 50s.

Other great options which don’t contain the hormone estrogen include IUDs, implants, shots and minipills. Some IUDs contain the hormone levonorgestrel, a kind of progestin, which helps decrease or even eliminate heavy menstrual bleeding, a common problem for women in their 40s. These types of IUDs last three to five years.

Another kind of IUD is made of copper, does not contain hormones and can last up to 10 years. Both types of IUD and the contraceptive implant, a small flexible rod which is inserted under the skin of your arm for three years of birth control, are collectively called long-acting reversible contraception (LARC). They are more effective than pills, patch or ring, don’t contain the hormone estrogen (so women who cannot use estrogen can use these), and can protect you against pregnancy for several years.

Just in case you had unprotected sex and you don’t wish to become pregnant, there are also several kinds of emergency contraception, previously known as the morning after pill. There are pills called Plan B One-Step which you can get at your local pharmacy without a prescription. They contain the hormone levonorgestrel and delay ovulation or release of an egg. They do not interfere with an established pregnancy or cause a miscarriage. Plan B should be taken as soon as possible after unprotected sex but must be taken within 72 hours.

Another option that is more effective, especially if you are heavier, is Ella. Ella is effective in decreasing the risk of pregnancy up to five days after unprotected sex but requires a prescription. A copper IUD inserted within five days of unprotected sex is the most effective option for emergency contraception but requires an appointment with a health care provider. The advantage of the IUD is that you can keep it for birth control for up to 10 years.

Once you have missed your period for a year, you are considered menopausal and may safely stop birth control. About 90 to 95 per cent of women will be menopausal by age 55 and may stop birth control then.Even before the final period, many women experience menopausal symptoms such as hot flashes and trouble sleeping.

You can start on menopausal hormone therapy using an estrogen patch to help manage symptoms and use one of the progestin-only birth control options for contraception and to protect the uterine lining from growing too much with the estrogen
