Nuva-ring: this is not because you left your nuva ring in to long. the only problem leaving it in too long, is it has a reduced estrogen/progesterone contact, and thus risk for pregnancy is higher. i feel something else is occurring in your body causing fatigue, and pain. Get evaluated by your PCP. I would suggest base line labs first, CBC and BMP.
