Both of you were too drunk and decided to enjoy a night of steamy passion without using a condom. The next morning you woke up with a heavy head and an 'oops! I did it again' feeling. Worry not? You might still avoid the chances of an unwanted pregnancy. There are pills that you can take the morning after having sex.

The pill is packed with a high dose of synthetic hormones that interferes with the fertilisation process.
