 [ Symptoms ] i have not had a period in over 2 5 yrs do i need to stay on the pill [ Disease ] i suggest you call the physician who is treating you for the atrial fibrillation afib if you were diagnosed at the hospital and do not yet have a cardiologist then you certainly could return to the hospital however your best bet is to get set up asap with a cardiologist since afib requires lifetime management in general we like patients to maintain oxygen saturation levels above 90 if your levels were above 90 when you left the hospital but have dipped to 83 and stay there consistently then i do suggest you try to see your primary care provider or go to an urgent care facility wishing you well
