Irregular Intake Of Birth Control. Lead To Spotting And Period

Irregular intake of birth control.
Lead to spotting and period starting at end of 3rd row of pills. Usually if I miss it, it last the 3rd row of pills week and stops. This time its been 2 weeks and I'm still on my period. Experienced cramping and dizzyness and then tried tampons for for the first time which made the situation worse. More dizzyness, stomach cramping, headache, dont really know what I'm doing (light headed). The period flow has been consistent.
