Hi, So I Am On Birth Control To Help With

Hi, so I am on birth control to help with the pain that comes with my menstural cycle. I skipped two months of activation pills due to being on vacation. My regular gynecologist assured me it would be fine. Well I have just started a new month and was planning to take all pills necessary for this month when I started menstruating for over a week now. It happens during the day but subsided at night. And I’m not sure what to do or if something is wrong.
