No, most forms of birth control are not effective immediately, so you want to check with you doctor before having unprotected sex. Until then, use a condom for added protection.

Does birth control cause blood clots?
Progestin-only methods like the implant, mini-pill, the shot, and Skyla and Mirena IUDs don’t increase your risk. If you’re worried about blood clots, we recommend talking to your doctor about which birth control options are best for you.
Using a method of birth control with estrogen increases a young woman’s risk of forming a blood clot by several times, but for women who have no history of stroke, blood clots, or heart attack, and whose family members have never experienced a blood clot, the risk is still quite low. Women with a history of these medical conditions in their family have a higher risk of forming a new blood clot; adding birth control with estrogen to the mix increases that risk to an unacceptable level.

Should the pill be available without a prescription?
Women in over 80 countries can already buy the pill without a prescription—including women just across the border in Mexico. As medications go, the pill is very safe—safer than having a baby, driving, smoking, or taking daily aspirin.
That said, the pill does have risks for women with certain medical conditions, but one study in El Paso showed that women who answered 15 questions were pretty accurate in choosing whether the pill was safe for them.
Doctors have argued since 1968 that the pill can safely be sold over-the-counter. That means rather than go to a doctor or clinic for a prescription, a woman could go to a drug store to pick up a pack of pills in the same way she can now buy aspirin. Behind-the-counter means a woman would ask a pharmacist for the pill, but she still wouldn’t need a prescription from a doctor. Over 50 drugs that were once prescription-only are now OTC in the U.S., including Sudafed, Cortaid, Advil, Nyquil, Monistat, and Claritin.

Can the pill help protect you from ovarian cancer?
The pill offered the strongest protection from ovarian cancer when women used it for a year or longer. Women who used the pill for 10 years were 50% less likely to develop ovarian cancer. The pill’s protective effect lasted for a long time, too—up to 20 years after women stopped taking it.
Yes. A group of scientists in the North Carolina Research Triangle put together all the studies printed after 1990 that look at women using the pill and their rates of ovarian cancer. They found that women who had ever used the pill for birth control were 25% less likely to develop ovarian cancer later in their lives.

What's an ovarian cyst?
A cyst is basically a bubble—a collection of fluid with a thin wall around it. Functional cysts are formed when a follicle (the fluid-filled sac that develops around an egg during ovulation) grows larger than expected. Sometimes they can cause un-fun symptoms like abdominal discomfort, pelvic pain, pain during bowel movements, or pain during sex. Most cysts disappear on their own, but if they keep growing they can cause severe pelvic pain or pain that causes dizziness or fainting and comes with a fever or vomiting. If you have any of these severe symptoms, go see your health care provider ASAP. Some hormonal birth control methods—the ones that work by blocking ovulation—may mean fewer ovarian cysts. If you tend to get cysts, your provider might recommend you try a method like the pill, the ring, the patch, or the shot.
What is levonorgestrel?
Levonorgestrel is one of the longest-studied types of progestin, and all the scientific evidence to date shows it is super safe. It’s used in hormonal IUDs, some emergency contraception pills, and certain birth control pills.
I threw up right after taking my pill. Now what?
If you throw up within two hours of taking your pill, treat it as a missed pill and take the next pill in your pack right away. Depending on which type of pill you use and where you are in your pill pack, you may need to use a back-up method like condoms for the next seven days to prevent pregnancy.
Is it safe to take the pill for years without a break?
There’s been lots of research on birth control pills over the years and the consensus is that long-term use doesn’t affect your ability to get pregnant once you stop taking the pill. It’s always a good idea to stay current on your annual health exams, whether you use the pill or another method. Our health changes over time, and some changes like rising blood pressure or worse migraines may make it risky to use methods with estrogen.
The short answer is yes—there’s no reason to take a break from the pill unless you’ve decided you want to get pregnant. That’s true for continuous use of the pill too—although if you experience spotting, you may want to take an occasional break (3 days minimum, 7 days max) to manage it.
