What is the difference between the mini pill (micronor) and the pill (migrogynon)?
It is difficult to add much when my answers follow Rhianna’s. The depth of her knowledge puts that of some doctors I know to shame. Microgynon is an oestrogen + a progesterone, Ethinylestradiol + Levonorgestrel. It is taken for 21 days in a row, this causes some build up of proliferative endometrium, though less that would be the case on no contraception. Thus 7 pill free days are needed for this to be shed, resulting in a pill withdrawal bleed, which is therefore lighter than a true period. It is very unusual to have continuous bleeding on this pill and this would require investigation to exclude all causes of bleeding. Micronor only contains a progesterone, norethisterone, this does not really stimulate much endometrial activity, but there can frequently be light and continuous bleeding on it for commonly 3 and occasionally as long as 6 months. However with ongoing use, since there is little or no endometrium to shed, 70% of women cease to have any bleeding by one year.
