Full question: "Is it normal to have periods that are painful for the first day that I cannot function without ibuprofen and are really heavy like the extra heavy pads cant contain the blood for more than 4-5 hours or else I have an accident?"
It depends. Period flow and pain are all relative, so it might be “normal," but it might not be! Our best advice here is for you to see a doctor. Even it your period is found to be "normal," there are treatments that your doctor can give you to decrease the pain and bleeding!
