So, for whatever reason, contraception wasn’t used – or something went wrong – and unprotected sex took place. It happens, it’s what you do next that counts. Using ellaOne can reduce your chances of getting pregnant to just 9 in 1000*.
When your partner ejaculates into your vagina (or sperm comes into contact with the vagina during other sexual activities) the sperm start doing what sperm do best: looking for an egg. They will swim from the vagina, through the cervix, all the way to the fallopian tubes where they wait for an egg to be released as a result of ovulation.
Sperm can survive in the reproductive system for up to five days, ellaOne can work by preventing ovulation until all the sperm have died. This means that there’s no egg to fertilise so no pregnancy can take place.
Even though you use oral emergency contraception after unprotected sex, it’s still a preventative method. The morning after pill can not terminate a pregnancy and there is no evidence to suggest it can interrupt an existing pregnancy. .
Deborah says: “Unfortunately, if you have recently ovulated, then the morning after pill won’t be effective. However, ovulation can be difficult to pinpoint and can vary from month to month.”
