I have been on microgynon for just over 2 years now and for the first time i started a period 1 week after finishing the normal withdrawel bleeding. I've not skipped any pills so personally i see no reason for it to be happening. This period is alot heavier than usual. It has been heavy for 4 days and is showing no signs of lightening up, where usually my withdrawel bleeding only lasts about 5 days in total.

Any ideas? o.O
