Norethisterone Effects on Pregnancy

Norethisterone is an effective drug in delaying your period, but it is not an effective form of contraception. There is the possibility of becoming pregnant whilst using Norethisterone, but this must be monitored closely because Norethisterone is not an appropriate drug to be used whilst you are pregnant.

Pregnancy: the signs

If you are pregnant, there are a number of changes to your body which signal whether you are pregnant or not. Some of these signs include:


  • Missing a period
  • Feelings of sickness/nausea
  • Feeling very tired
  • Tender breasts
  • Stomach cramps
  • An odd taste in your mouth (often described as metallic tasting)
  • Change in appetite
  • Needing to urinate more often
  • Increase in vaginal discharge
  • Constipation

However, if you take Norethisterone, it will be harder to tell if you are pregnant as you won’t be able to use your period as an indicator. If you suspect pregnancy, you must take a pregnancy test or go see a medical professional to determine whether you are pregnant or not.

Can I use Norethisterone during pregnancy?

It is established that Norethisterone should not be used during pregnancy, or even if you suspect that you are pregnant. If you happen to become pregnant when using Norethisterone, it is important to inform your doctor immediately and stop taking the drug. If you keep taking Norethisterone during pregnancy, this could interrupt the production of breast milk and change the composition of the milk, which could potentially be harmful to your baby.

Can I use Norethisterone after giving birth?

Because of the possible effect of Norethisterone on breast milk, you should not take Norethisterone immediately after having a baby. If you take Norethisterone, it could negatively affect your breast feeding process with your baby, which could potentially affect the overall growth and development of your child.
