So i put the nuva ring in like my doctor said toand i had it in for 3 weeks and took it out on sunday when the 3 weeks ended for the one week that wasnt supposed to be in for. Then;exactly one week i put it back in on the following sunday like you are supposed to. But my period wasnt over yet untill Monday. It never fell out ot anything and then i had unprotected sex for the first time saturday night 6 days after i put it back in.. are you supposed to wait 7 days after you put a new one in everytime to have unprotected sex?
