The risk of getting pregnant is there since you have unprotected sex.
If this is worrying you sick, try to get some After-Morning Pills which no prescription is required but can only purchase it (here in SG at least) in the presence of a Pharmacist.
The morning-after pill stops you from becoming pregnant, after unprotected sex.
Although lots of people talk about the morning-after pill, this term is actually misleading.
In reality, the traditional type of tablet works for up to 72 hours (three days) after sex – not just the morning after. And the newer version, introduced in 2010, should work for up to FIVE days after intercourse.
But the earlier you take it, the better: the morning-after pill works best if taken within 12 hours of unprotected sex.
Medical professionals dont't use the term morning after pill. They call it the post-coital pill (PCP) or – in Britain – the emergency contraceptive (EC).
Taking the emergency contraceptive used to involve taking TWO pills, separated by an interval. But these days, you only have to swallow a single tablet.
