Many women take certain birth control pills to regulate their acne. Once you stop using birth control, you may notice an increase in acne on your face or on other parts of your body. When your body's hormone levels regulate again, the acne can subside in some cases.

Can women older than age 35 continue taking birth control pills? If you're healthy and you don't smoke, you can continue taking birth control pills after age 35. However, birth control pills aren't recommended if you're 35 or older and you smoke because of the risk of cardiovascular disease.

There is a misconception amongst some women that, once off the Pill, it takes time for fertility to return. This is simply not the case. Your ability to conceive returns immediately (barring individual complications, of course) as soon as you stop ingesting the extra estrogen or progesterone.

To begin, the birth control pill works by preventing ovulation. Once you stop taking the pill, the hormones are out of your body quickly, usually within a couple of days (this is why women who miss a couple days of pills on birth control have a chance of ovulating and getting pregnant!).

It takes a while for your periods to come back after you stop taking the pill. Most women will have a period around two to four weeks after stopping the pill, but this depends on you and what your cycle is normally like. Weight, health, stress, exercise and conditions such as polycystic ovary syndrome (PCOS) can all influence your cycle of periods.

While it is true, some women get pregnant on the pill, some miss a pill and get pregnant and some come off only to get pregnant right away. You will need to remember that there are many other women whose bodies take time to regulate after stopping these hormones.

Your periods may be irregular when you first come off the pill, and you should allow up to three months for your natural menstrual cycle to re-establish itself fully. This is because the pill contains the hormones that stop ovulation (the release of an egg) each month.

In terms of your overall health, it makes little difference when you stop taking the pill. When you finally do stop the pill, you can expect some bleeding, which may change the rhythm of your menstrual cycle. But you can stop at any time.

Age matters when predicting this outcome. If you began taking birth control when you were a pubescent 15 year old, then there is a chance you'll have outgrown your acne if you stop using it as an adult. Another skin-related side effect that some women on the Pill experience is sun sensitivity.

Women are starting to take advantage of newer birth control methods that have the positives of the Pill, but less of the drawbacks. Over the past 30 years, the IUD has become increasingly popular, thanks to less hormones and three to ten years of protection.
