Overview
The contraceptive pill is a method of birth control that involves taking a tablet at the same time each day to prevent pregnancy. It comes in different types including the combined pill, which contains both oestrogen and progesterone, and the mini-pill, which contains only progestin. Apart from preventing pregnancy, it can also help regulate menstrual cycles.
When taken correctly, the pill is over 99% effective at preventing pregnancy. In real world use, about 8 in 100 women who use the pill a year become pregnant due to incorrect use such as forgetting to take pills (92% effective).
You need to take the pill at the same time every day. You could get pregnant if you miss a pill, or vomit or have severe diarrhoea.
There can be a very low risk of side effects, such as blood clots and cervical cancer.
The pill does not protect against sexually transmitted infections (STIs). You need to use a condom as well to help protect you against STIs.
