Emergency contraception is taken if the normal contraceptives have failed. They prevent pregnancies, but do not interfere with existing pregnancies. The pill will suppress an ovulation making it harder for the egg to be fertilized. If you take a pill when you are pregnant, it does not affect the fetus.
Plan B is available over-the-counter to all women. Ella is available to all, but only with a prescription. It is recommended to take it 72 hours after unprotected sex, but the pill is most effective within 12 hours. The prescription-only pill Ella can be taken after 5 days.
The side effects can be more or less the same as any birth control pills. The potential health risks of an unplanned pregnancy are higher than any potential harm from the morning-after pill.
Regular use of birth control, such as condoms and pills, is more effective to prevent pregnancies. Emergency contraception is also more expensive, $50. So it’s cheaper to use other contraceptives.
It won’t do any harm taking it more than once, but do not use it instead of birth control. Still, it is not recommended to use it more than once.
If you’ve had unprotected sex neither of the different emergency contraceptives will protect you against infections or sexually transmitted diseases. Condoms are the only form of birth control that will protect you against it.
