Finally, POPs will not prevent functional ovarian cysts as well as the combination oral contraceptive. POPs do not contain estrogen. Therefore they can be used by women who cannot or should not use combined oral contraceptives, such as women with a history of blood clots, severe migraine headaches, high blood pressure, or cigarette smokers over the age of 35. Women who are breast-feeding can use POPs for contraception. Using POPs while breast-feeding will not harm a baby and may actually help increase the amount of milk produced.
POPs have a number of noncontraceptive benefits.
POPs offer reversibility. Ovulation is reestablished quickly after discontinuation. POPs do not cause infertility. It's best to start the pills the first day of your period. The pill is taken every day at the same time.
