Question: how likely are you to get pregnant on cerelle?
Answer: If taken correctly, it's more than 99% effective. This means fewer than 1 woman in 100 who uses the progestogen-only pill as contraception will get pregnant in 1 year. With "typical use" of the progestogen-only pill (the way it's taken by a lot of women in real life), it's only about 92% effective.
