Yaz is an oral contraceptive that contains drospirenone and ethinyl estradiol. It is used to prevent pregnancy and the treatment of premenstrual dysphoric disorder. Yaz may also be used for the treatment of acne in women that are using Yaz for birth control, says Drugs.com. Oral contraceptives work by inhibiting ovulation and altering the uterine lining and cervical mucous. They do not prevent sexually transmitted infection or HIV transmission. Women who stop taking the Yaz birth control pill may experience side effects.
Menstrual Irregularity
While a woman takes Yaz, her body adjusts to a heightened hormonal level. When the medication is stopped, it may take a while for the body's hormonal level to return to normal. Women may experience menstrual irregularity for a few months after stopping Yaz. It may take a few weeks for their period to return, and resume a normal schedule. Breakthrough bleeding and spotting can occur during this time. Women who did not have a regular menstrual cycle prior to taking Yaz should not expect to have a normal cycle after they stop taking the pill.
Impaired Fertility
Women may experience a delay in being able to conceive after stopping oral contraceptive use. Those who have an irregular cycle prior to taking Yaz may be more likely to experience impaired fertility. It can take several months for a woman's body to ovulate after stopping the pill. Those who wish to become pregnant may want to wait until they have at least one menstrual cycle to begin trying to conceive. In doing so, it will be somewhat easier to estimate the time of ovulation and when the baby is due, says MayoClinic.com. If several months pass and pregnancy does not occur, a woman can consult her gynecologist for additional instruction.
Amenorrhea
Some women may experience an absence of menstruation, or amenorrhea after they stop taking Yaz. This is also known as post-pill amenorrhea, reports MayoClinic.com. Those who do not begin menstruating within several weeks of stopping Yaz should take a pregnancy test to make sure they are not pregnant. A gynecologist should be consulted if more than 6 months pass without a menstrual period.
