I have been taking Nortrel 7/7/7 for about a year and a half now. Two days ago I took the last row... (the non-active row - which starts your period) on accident - skipping the third row. I was wondering if I should jump back up to the third row? Or continue taking the last row (the white pills) - as I have my period now. Also- when I am finished taking the row I am on, should I start a new pack? Thanks!
