What is the Noriday pill?

Noriday is a type of oral contraceptive pill (OCP) that only contains one type of hormone. This is a progestogen called norethisterone, and helps to prevent pregnancy by making the cervical fluid in the womb thicker. By doing this, sperm can’t swim through to an egg quite as easily to fertilise it.

Progestogen-only pills, or POPs, like Noriday also stop ovulation in some women. This means that the ovary doesn’t release an egg. So even if a sperm did make it through the cervix, there would be no egg to fertilise.

Combined oral contraceptive pills (COCPs) tend to be more widely taken than progestogen-only pills. But POPs like Noriday are recommended for women who can’t take combined birth control because they have a health factor that makes them sensitive to oestrogen (such as migraines).

How do Noriday tablets stop you getting pregnant?

Every month, your body goes through a checklist of things to prepare for pregnancy. During ovulation, the ovary releases an egg which travels through the fallopian tubes towards the uterus. If the egg is fertilised as it travels, it attaches to the uterine wall and starts growing. If it isn’t fertilised, you get your period and it’s better luck next time.

All of this happens because of rising and falling levels of hormones. Hormones trigger ovulation as well as smaller changes, like telling the wall of the uterus to become thicker so that it’s easier for a fertilised egg to attach itself there.

The hormone in Noriday, norethisterone, is a type of progestogen. Adding it to the hormones already in your body alters what happens every month. Norethisterone increases the density of cervical fluid, so sperm cannot swim through and reach an egg as easily. Some of the time, the progestogen in mini pills totally overrides the normal hormonal cycle, preventing ovulation, so fertilisation can’t happen.

What you need to know about Noriday

How does Noriday work?

The hormones in Noriday change what happens in your body every month when it would normally get ready for pregnancy.

Noriday makes fluid in the cervix more dense, which acts as a barrier to sperm and means that fertilisation is much less likely. In some women, Noriday also prevents ovulation. Without ovulation, no egg is released into the uterus.
