Plan B Pills and Pregnancy
Emergency contraception is a method of preventing pregnancy, if:
- You have had sex without protection.
- Your contraceptive method has failed. Perhaps you forgot to take a pill or make an injection, the condom broke or slipped off, or your diaphragm slipped.
- You were raped. Even if you use contraception, emergency contraception can help you verify that you are not pregnant.
If you had sex without protection, there is a chance that you could get pregnant. This can happen even if you still don’t have a period or approaching menopause. You can get pregnant in case if you use not a very reliable method of birth control or in the case of its improper use.
How Long Does Plan B Prevent Pregnancy
Pills used for emergency contraception sometimes referred to as "post-coital contraceptives." They can be taken at any time during 5 days after unprotected intercourse, but the sooner the better. They contain progestin hormone or a combination of estrogen with progestin.
Plan B is a drug containing only progestin that is used specifically for emergency contraception. Plan b works better and has fewer side effects than contraceptive pills. These pills are considered to be the best. Package for single use (2 pills).
How it Works
The emergency contraceptive pill prevents ovulation, fertilization or implantation. Emergency contraceptive hormones can prevent fertilization, by preventing the release of an egg from the ovary. They can also prevent the passage of the egg to the uterus via the fallopian tubes. It is believed that emergency contraception also reduces the uterine lining, or endometrium. Increased endometrium is the place of attachment and development of a fertilized egg.
How to Use Tablets
If you decide to take Plan B, you will need to take 2 pills as soon as possible. Or 1 pill immediately, and another one in 12 hours. The first dose can be taken for 5 days after unprotected intercourse, but it will work most effectively when taken within 48 hours.
Pregnancy Symptoms After Plan B
Sometimes emergency contraception methods fail and pregnancy occurs. Do drugs have a negative effect on the fetus?
In some cases, in order to prevent unwanted pregnancy, you should undertake activities after unprotected intercourse. This contraceptive method is called emergency or post-coital. To date, there are special devices (IUDs), as well as medications for emergency (urgent) prevention of an unwanted pregnancy.
However, none of the existing methods of emergency contraception gives 100 % guarantee of efficiency. There is always a risk that the drug might not work, and successfully fertilized egg attaches to the lining of the uterus. In this case, the question arises: do emergency contraceptives have a negative effect on the fetus? Should a woman terminate a pregnancy (abortion) if emergency contraception fails?
Does Plan B Prevent Pregnancy in the Future
Does the plan b pill affect future pregnancy? There are currently no reliable data, pointing to the fact that emergency contraception when ineffective have an adverse effect on the fetus. At the same time, it is also impossible to completely eliminate the likelihood of anomalies, because the fetus is affected by many other factors.
If after taking emergency contraception pregnancy still occur, and the woman decides to keep the baby, she must be closely monitored at the gynecologist. Ultrasonography can help determine the location of the fetus, since relatively common side effect after unsuccessful emergency contraception is an ectopic pregnancy. For example, it is known that the installation of intrauterine copper spirals increases the likelihood of ectopic pregnancy.
The risk of ectopic pregnancy also increases when taking gestagenic drugs for emergency contraception. It is known that levonorgestrel inhibits egg speed in the uterine tubes, that on the one hand reduces the likelihood of fertilization, and, on the other hand, increases the risk of ectopic pregnancy.
