Problem with the birth controll pill seasonale?

I'm on the birth controll pill seasonale. It alllows you to have a period only every 3 months. about a month ago I accidenlily went away and forgot my birth controll pills. I missed two days of the pill, since then i have had spotting and bleeding that wont stop. the first week was just spotting, the second week it was worse, the third week was on again and off again bleeding. Now its been almost 4 weeks and im geting really ticked off/worried that somethings wrong. This is especially wird becouse I ususlly only get 3-4 day periods and I am not realy heavy so i dont know why the blood keeps comming. i have also taken the pill every day since. what can i do to make it stop?
