Types of Emergency Contraception
What is the difference between emergency contraception,
the "morning after pill", and the "day after pill"?
Actually, there is no difference.
Emergency contraceptive pills are often called "morning after pills" and ometimes even "day after pills" because you can use them after sex to prevent pregnancy. Most of the time, when someone mentions “emergency contraceptive pills,” “morning after pills,” or the “day after pill,” they are talking about using the same hormones found in regular daily oral contraceptive pills to reduce your chances of becoming pregnant if you had sex without using contraception, you think your birth control failed, or you were forced to have sex.
Even though there’s no difference between these terms, calling emergency contraceptive pills “morning after pills” or “day after pills” can be misleading because you can use them right away – and you have up to 120 hours (five days) after sex to take the pills and still prevent pregnancy. That means you don’t have to wait until the morning after, and you can still use emergency contraception even if it takes you longer than the morning after to get it (Need to get it now in the U.S?

Some people get confused and think that emergency contraceptive pills, or morning after pills, are the same as “abortion pills” They aren’t. First, RU-486 (also known as the French abortion pill, mifepristone, and Mifeprex) contains a completely different drug than the hormones found in the birth control pills used for emergency contraception. Second, emergency contraceptive pills prevent pregnancy, so they work differently than the abortion pill.
