The combination of hormones in Microgynon 30 slows down ovulation. In this way, an egg is not released during the cycle. In addition, the contraceptive pill makes a woman’s reproductive organ less suitable for sperm and a possibly fertilized egg. The sperm will have a more difficult time entering the egg, and the uterus is less suitable for the egg to nest. This birth control pill is often prescribed. The pill is relatively light, and users typically notice few side effects. If you notice any side effects, you will need to contact your doctor or use another method of contraception. Microgynon 30 is taken every day around the same time (thus reducing the chance of forgetting it). One strip of Microgynon 30 contains 21 pills with the day they are to be taken. When a strip is emptied, a 7-day week of no pill is started. In this week there is bleeding that looks like menstruation. After that week a new strip of Microgynon 30 is started.
