Pill Periods In The Weeks Still Taking The Pill

I have been on the pill for about 9 months and an resantly am having trouble with it. The last two months i have had too skip leaving a month to have my period because of activities that would not be completed if ii was on , so i stopped it. However the last week and a half (the week i was ment to be on and the following week )i have still had a period even tho i stopped it. And it has no signs of stopping. What do i do?
