Side effects of the pill

The combined contraceptive pill is usually referred to as ‘the pill’ and it contains the hormones oestrogen and progesterone. When taken correctly, the pill is over 99% effective at preventing pregnancy*.
The pill prevents pregnancy by stopping you from releasing an egg each month. The hormones in the pill also thicken the mucus in the neck of your uterus (womb) making it difficult for sperm to reach an egg. The womb lining is also thinned so that a fertilised egg finds it difficult to implant itself onto the wall of your womb.
What are the side effects of taking the pill?
Many women experience temporary side effects when they start taking the pill; these usually subside after a few months.
