It doesn't make you un-pregnant. It prevents ovulation. Picture it being the birth control pill but a much higher dose. It can be taken up to 72 hours after the unprotected sex to be effective. It is two pills, taken within 12 hours of eachother. It could cause nausea, if you are sensitive to hormones. Sometimes the birth control pill can cause a bit of nausea. Here is some other information on PlanB:
1. What is Plan B®?
Plan B® is emergency contraception—a backup method of preventing pregnancy—and is not for routine use. It can reduce the chance of pregnancy when taken as directed up to 72 hours (3 days) after unprotected sex (if your regular birth control method fails, or if you've had sex without birth control).
2. How does Plan B® work?
Plan B® contains two pills taken 12 hours apart that contain a higher dose of levonorgestrel, a hormone found in many birth control pills that healthcare professionals have been prescribing for more than 35 years. Plan B® works in a similar way to prevent pregnancy. Plan B® will not affect an existing pregnancy.
3. When is it appropriate to use Plan B®?
You can use Plan B® after you've had unprotected sex one or more times in the last 72 hours (3 days), and you don't want to become pregnant.
Plan B® can be used as a backup method to birth control if, for example:
* Your regular birth control failed (your partner's condom broke or slipped)
* You made a mistake with your regular method (you forgot to take your birth control pills)
* You didn't use any birth control method
4. When is it not appropriate to use Plan B®?
Plan B® should not be used:
* If you're already pregnant, because it won't work
* If you're allergic to levonorgestrel or any of the ingredients in Plan B®
* In place of regular birth control. Plan B® should not be used as routine birth control, as it's not as effective. Plan B® won't protect you from HIV infection (the virus that causes AIDS) and any other sexually transmitted disease (STD).
5. When should I use Plan B®?
You only have a few days to prevent pregnancy after unprotected sex. Plan B® works better the sooner you take it. Take the first pill as soon as possible (within 72 hours after unprotected sex), and the second pill 12 hours later.
6. How effective is Plan B®?
Plan B® works better the sooner you use it. If it is taken as directed within 72 hours (3 days) after unprotected sex, it can significantly decrease the chance that you will become pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant. Plan B® works even better if taken within the first 24 hours after unprotected sex.
7. How will I know if Plan B® worked?
The only way of knowing Plan B® has been effective is when you get your next period, which should come at the expected time, or within a week of the expected time. If your period is more than 7 days late, you may be pregnant.
8. What if I'm already pregnant and use Plan B®?
There is no medical evidence that Plan B® would harm a developing baby. If you take Plan B® accidentally after you're already pregnant, or it doesn't work and you become pregnant, it's not likely to cause any harm to you or your pregnancy. Plan B® will not disrupt or affect an existing pregnancy.
9. Can I use Plan B® for regular birth control?
Plan B® should not be used as regular birth control. Plan B® is not as effective as using a regular birth control method correctly and consistently. It is a backup method to be used if your regular birth control fails, or if you have sex without birth control. If you have unprotected sex after taking Plan B®, it cannot protect you from getting pregnant.
10. How often can I use Plan B®?
Plan B® should only be used in emergencies, but there is no medical reason why you can't use it more than once. Don't be afraid to use Plan B® when you need to, but remember that it should never replace routine methods of contraception as it simply isn't as effective.
Plan B® doesn't provide long-term protection against future pregnancy—it only works to prevent this one incident. If you are sexually active, even occasionally, see your healthcare professional or clinic to find a method of birth control and STD prevention that suits you.
11. Will I experience any side effects from Plan B®?
When used as directed, Plan B® is safe and effective. Side effects may include nausea, abdominal pain, headache, dizziness or breast tenderness. Some women may have changes in their period, a heavier or lighter next period, or a period that is early or late. If your period is more than a week late, you may be pregnant. If you have severe abdominal pain, you may have an ectopic pregnancy, and should get immediate medical attention.
12. What warnings should I know about when using Plan B®?
Do not use Plan B®:
* If you're already pregnant, because it won't work
* If you're allergi
