Emergency contraception, or the morning after pill, or plan B – there are different types, or different brands, I should say, of the same type of pill – is basically a very intense dosage of the pill – hormones, just hormones is what they are. And what it does is basically prevents ovulation from happening. It also builds up the mucus inside the cervix to prevent the sperm from going through and it causes the lining of the uterus not to form quickly. If somebody is already pregnant, the morning after pill will not prevent the pregnancy, will not terminate the pregnancy. It can be used 3 to 5 days after unprotected sex. What ends up happening, it’s better to use it within 3 days, it can be 89% effective if you use it within those 3 days, but it can go up to 5 days to use the pill to prevent the pregnancy. It is not recommended that this particular type of birth control, the morning after pill, be used as a way of preventing pregnancy on a regular basis. It is meant for emergency purposes only. If somebody wants to prevent pregnancy, then they have to use a different type of method and they have to see their healthcare provider to find something that works best for them.
