i've been on nuva ring for a year and i've had nothing but good experiences with it. i've always used it perfectly. i put it in and take it out on sunday evenings, always. this is my third week with the ring in and i started my period on thursday, two days ago. so about a full week early (my periods don't normally start until the tuesday or wednesday after i take the ring out). thursday it was light but yesterday (and now today) it's a normal period with all the normal symptoms. Should I be concerned? Should I leave the ring in until Sunday (tomorrow) night like I normally would? Or take it out now?
