How does the pill work?

Dr Louisa Draper

"The combined contraceptive pill prevents pregnancy in three ways, making it a very effective contraceptive choice. It prevents ovulation, thickens the mucus at the entrance to the womb to prevent sperm getting in, and alters the lining of the womb to prevent an egg from growing there."

Common Myths About The Pill

Myth: The pill is like an abortion.

Truth: The pill is a contraceptive, which prevents that an egg can get fertilised and implant in the womb. It does not work if you are already pregnant.

Myth: The pill does not work if you are overweight.

Truth: This is incorrect, the pill also works for women who have a high BMI. However, women who are very obese or have an otherwise increased risk of thrombosis are often advised to take a mini pill rather than a combined pill.

Myth: The pill is for contraception only.


Truth: The pill is not only prescribed for the purpose of contraception but it is also used to treat severe acne as well as menstrual disorders.

Myth: You can’t get pregnant if you have been taking the pill for a long time.

Truth: The pill only works as long as you take it. It does not decrease your fertility in the long term.
