Unusual period

Harriet • ☁️

I started Microgynon, the combined pill, and have been on it for 2 months and have got my period whilst still on active pills instead of the inactive ones when I’m supposed to, it’s been 11 days which is twice as long as my natural period and I’m still bleeding and have had bad cramps every day instead of only the first and second day when I was not on the pill, should I be worried?
