Emergency Contraception || Understanding What It Is

What is it?

Emergency contraception, often referred to as the morning-after pill or day-after pill, contains a high dosage of synthetic hormones. The way it works varies depending on the timing of your menstrual cycle. It's important to note that emergency contraception can potentially prevent pregnancy either before or shortly after implantation. However, its effectiveness is not guaranteed in all cases.

It's essential to understand that the morning-after pill is not a substitute for regular birth control methods. Manufacturers explicitly state that it should not be used as a routine form of contraception. Additionally, it does not provide ongoing protection for future sexual encounters.

What its purpose?

Women most commonly seek emergency contraceptives when they fear pregnancy in situations like:

  • A contraceptive method was desired but not used.

  • A contraceptive failure—a condom broke, diaphragm or cervical cap breakage, or a barrier contraceptive slippage.

  • Birth control pills, patches, rings, or injections are started late or dislodged.

  • Failed withdrawal.

  • Expulsion of an IUD or implant.

  • Sexual assault; forced sexual intercourse.

How does it work?

Hormonal emergency contraception works to thin the lining of the uterus and sometimes prevent ovulation. During the time of your cycle when you can conceive, it often fails to act as a contraceptive & acts instead as an abortifacient.

High doses of synthetic hormones may carry health risks. If you have any existing health conditions, be sure to discuss these with your doctor before you buy or take emergency contraception. Side effects of hormonal emergency contraception, which typically last a few days, can include headache, nausea/vomiting, dizziness, fatigue, breast tenderness, changes in menstrual bleeding, and abdominal pain.

If you have noticed any unexpected side effects, such as heavy bleeding, seek medical attention right away.
