Probably worrying about nothing but.... I have been on Microgynon for about 8 years now. At first it would take about 3 days after finishing a pack for my period to start. After a few years it became 4 days in between and then recently it has been 5 days in between. I took the last pill on Monday and still no period today so looks like it might even be 6 days now in between. (I'm definitely not pregnant by the way). Is this normal? Should I be worrying about it? Thanks to anyone that can shed any light.
