The morning after pill is a form of emergency contraception that can be taken as many as 5 days after unprotected sexual intercourse to help reduce the risk of becoming pregnant. Although not perfect, it is quite effective in this setting.
However the morning after pill is not a form of regular contraception and it should never be used as such. "How long" the morning after pill might prevent pregnancy after taking it is not clear or well understood. The morning after pill is only meant to be used to prevent pregnancy after having already had sex. It is never intended to be relied upon as a way to prevent pregnancy from future sex acts.
It sounds like you need to have a regular form of contraception, which could be condoms or could be a birth control
pill or other medication. You should see your doctors
">primary care doctor or your OB GYN doctor about this issue as soon as possible so that they can help you decide which method is right for you. In the mean time, you should avoid unprotected sexual intercourse if you wish to avoid becoming pregnant.
