The pill and women in their 40s.
For women in their 40s, the pill can help ease the symptoms of perimenopause, such as hot flashes, night sweats and irregular monthly periods. And it can make your periods lighter and lessen cramps. If you don't want to become pregnant, you need birth control during perimenopause-even if your periods are not regular.
Fewer periods on the pill.
The newest birth control pills available limit your period to four times a year. The pill keeps the lining of your uterus very thin, which is why your period is light on the pill. Your period on the pill is a withdrawal bleed—your body bleeds in response to the withdrawal of the hormones. If you take the pill continuously, you will not have a withdrawal bleed. The lining of the uterus is not building up, it actually continues to be quite thin. In fact, it is not ever necessary to have a withdrawal bleed, and you could technically have no periods at all. This is the principal behind the newest pill on the market, in which you have a withdrawal bleed four times a year.
