Millions of women use contraception in the form of birth control pills. This allows them to have control over their pregnancy and body. Earlier, women had to depend only on condom, which would prevent a pregnancy but now it is not always so. Birth control pills can be used even after intercourse. Yes, we are talking about emergency contraception. You can use this type of contraception up to 120 hours or 5 days after sexual intercourse. It is important that you learn about the basics of this form of contraception so that you can make an informed decision about its use.
The use of emergency contraceptive pills was approved by the FDA in 2006 and since then millions of women have tried it. This pill works as a miracle pill for women who do not use other forms of contraceptives or after incidents such as tearing of the condom. Morning-after pills are also known as post-coital pills. These pills contain synthetic versions of two naturally occurring female sex hormones, oestrogen and progesterone. Most pills work in two ways: by preventing ovulation or delaying it and by preventing implantation of the fertilised egg in the womb. This can be done by altering the lining of the uterus in a way that the embryo fails to attach itself to the womb.
Sometimes, couples get caught up in the act and this does not give them enough time to use condoms or any other form of contraception. As per the advice of doctors, you can use emergency contraceptive pills within a time frame of 72 hours after having unprotected sexual intercourse and this will prevent you from getting pregnant. Using it after 3 days will not have any effect on ovulation and hence you might not be protected against an unwanted pregnancy. Some people think that a morning after pill can only be used the morning after you have unprotected sexual intercourse but it is not always so.
You can use these pills for up to 5 days after sexual intercourse. While the effectiveness of morning after pills is high during clinical trials, they do not give 100% warranty. There are more than 4-5% chances that a woman will get pregnant even after taking the pill. Most pills are really effective when taken within 12 hours of unprotected sexual intercourse. You should keep in mind that these pills are very different from abortion pills. Birth control pills are just a type of preventative measure against pregnancy.
Levonelle is an emergency contraception that works up to 72 hours after unprotected sexual intercourse. It works by preventing ovulation and fertilisation. How this medication works is not fully understood but it is known to be quite effective. Levonelle tricks the body into believing that ovulation has already occurred as it gives the body synthetic progesterone, which is responsible for preventing the release of eggs from the ovaries. Although there are very less side effects of this pill, it is always better to consult a doctor before using it.
