Taking Norethisterone while bleeding will not stop your period. This form of the contraceptive pill is designed to be taken every day throughout your menstrual cycle without a break. This means that you are meant to still be taking the pill even when you are on your period. It is a progesterone only pill so, unlike the combined pill, it does not regulate and control when your periods take place. You may find that when you are on norethisterone that you periods are quite irregular and may be infrequent, too frequent or missed completely. If you want to take a contraceptive pill that also regulates your periods then it is worth consulting your doctor and asking to be changed to a different form of birth control.
Norethisterone prevents pregnancy in three different ways. Firstly, it affects the natural mucus of the cervix. By thickening the mucus, the pill makes it more difficult for sperm to cross from the vagina into the womb. If this is more of a challenge then it is far less likely that a sperm will be able to reach the point where it would fertilize an egg. The pill also changes the quality of the womb lining. By making these changes, any eggs that are fertilised are unable to attach themselves and implant into the wall of the womb. Finally, norethisterone can help prevent the release of an egg from the ovaries completely. This is not something that occurs in all cases. In order for the pill to be most effective, it should be taken at the same time every day. It is suggested that if you take your pill more than three hours late, you will not be fully protected against pregnancy. Any sickness, diarrhoea or antibiotics can all have an effect on the efficiency of the pill so consider using another form of birth control if you have sex in any of these circumstances.
