So I went on the Nuva ring February 12th. I kept the ring in until March 3rd because it fell out
, I didn't bother to put it back in. Two days shy of 21 days, I should have taken it out March 5th. I didn't think I was going to continue usage of it, but today March 12th, I have inserted it again. I just finished my period and put it in today. It has been longer than seven days ring free.
My biggest issue is, when does the Nuva ring start to work? When is it effective or become effective?
