Spotting...? While taking the pill?

Hi everyone!
So I am on Jubler (birth control pill) and I'm supposed to take the 3 weeks and skip the last week; to stop my period. But I have been on it since March, and I'm sporting right now... I haven't been sexually active in about 3 weeks. I don't know what to do! I have been having what I think are cramps though in my lower stomach every day, some days worse than others I know I need to see a doctor, but it's really hard to find the time... Anyone help please!!
