Birth control pills were once only packaged as 21 days of active hormone pills and seven days of inactive pills.
While you take the inactive pills, menstrual-like bleeding occurs. Today you have many more options — from regimens with 24 days of active pills and four days of inactive pills to regimens that are all active pills.
Some extended-cycle pill regimens have active hormone pills every day for three months, followed by a week of inactive or low-dose estrogen pills. You experience menstrual-like bleeding during that week.
Other extended-cycle regimens involve taking active pills continuously for one year, which can stop all menstrual-like bleeding. Continuous or extended-cycle regimens have several potential benefits. They prevent the hormone changes that are responsible for bleeding, cramping, headaches and other period-related discomforts. They allow you to skip a period during important events or trips.
If you experience iron deficiency due to heavy menstrual bleeding, using continuous regimens can reduce bleeding. Unscheduled bleeding and spotting often occur during the first few months on continuous or extended-cycle regimens, but usually stop with time. There are birth control pill regimens designed to prevent bleeding for three months at a time or for as long as a year. But it's possible to prevent your period with continuous use of monophasic birth control pills — pills with the same hormone dose in the three weeks of active pills.
To prevent your period with these pills, don't take the inactive pills and start right away on a new pack. As soon as you ovulate again, you can get pregnant. If this happens during your first cycle off the pill, you may not have a period at all.
Take a pregnancy test if you've had unprotected sex and your period hasn't returned. Conceiving immediately after stopping the pill does not increase your risk of miscarriage or harm to the fetus. The hormones in birth control pills don't remain in your system. Usually periods start again a few weeks after stopping the pill.
However, if your periods were infrequent before you started taking the pill, they will likely be that way again after you stop taking the pill.
It may take a couple of months before you return to regular ovulation cycles. After stopping the pill, if you're not ready to conceive, consider using a backup form of birth control. If you don't have a period for several months, you may have what's known as post-pill amenorrhea.
The pill prevents your body from making hormones involved in ovulation and menstruation. When you stop taking the pill, it can take some time for your body to start producing these hormones again.
Menstrual periods typically resume within three months after you stop taking the pill. But if you took the pill to regulate your menstrual cycles, it may take several months before your period comes back. If you don't have a period within three months, take a pregnancy test to make sure you're not pregnant and then see your doctor.
You can get accurate results from a pregnancy test while you're on the pill. Pregnancy tests work by measuring a specific pregnancy-related hormone — human chorionic gonadotropin HCG — in your blood or urine. The active ingredients in birth control pills don't affect how a pregnancy test measures the level of HCG in your system.
Don't worry if you kept taking your birth control pill because you didn't know you were pregnant. Despite years of this accident happening, there's very little evidence that exposure to the hormones in birth control pills causes birth defects.

Used according to the instructions, Yaz is very effective as a form of birth control. Of course, real life is never quite as precise and perfect as a clinical study.
Although the main purpose of Yaz is to prevent pregnancy, it also works well as a treatment for acne. In fact, the FDA has approved Yaz as one of three birth control pills that can be used for treating hormonal acne outbreaks. Acne develops because of fluctuations in your levels of androgen hormones. This leads to blockages, which in turn can lead to acne outbreaks. If these blockages become infected with bacteria, they can become inflamed and painful, potentially leading to cystic acne and other serious skin issues.
With a lower average testosterone level, your body secretes less oil onto the skin, resulting in fewer clogged pores and acne lesions. Our guide to hormonal acne explains the role androgens play in acne in more detail, along with other effective treatments. Used alone, Yaz is normally effective at treating acne. Yaz also has several other benefits. Many women notice a shorter, easier period while using Yaz than before using hormonal birth control.
