What types of Emergency Contraception are available?
The "Morning After" Pill
What is it?
The "morning after" pill is a combined oral contraceptive which contains a high dose of the female hormones, estrogen and progestin. The morning after pill actually consists of four combined oral contraceptives tablets. You take two of the tablets with water immediately and two tablets 12 hours later.
How does it work?
The "morning after" pill should be taken as soon as possible after unprotected sex. Ideally, you should take the pills within 24 hours of having unprotected intercourse, but it can work up to 72 hours later.
The morning after pill works in the same way that OCs do - they prevent a pregnancy from starting by preventing ovulation. How effective is it?
Emergency contraception is very effective when taken as directed. The sooner you take it, the more effective it is. Ideally, you should try to take the "morning after" pill 24 hours after unprotected sex and no later than 72 hours.
If you are already pregnant, however, the morning after pill will not work. The morning after pill will not hurt the fetus. Are there side effects?
Nausea and vomiting are the most common side effects. These side effects can persist from a few hours to a few days. Serious side effects such as blood clots, heart attack and stroke are extremely rare.
If you want to put on a condom afterwards thats up to you.
