Hi there, I am currently on my last pack of Yasmin 21(birth control). I have 7 missing from when I returned home from a flight (the security lost it when the were checking bags). I currently went to a dr to get a new prescription for the nuva ring but she didn't advise me what to do for those missing 7 days. If I had those 7 pills my period should start on April 22. Should I use the nuva ring mid cycle and remove when I my period is scheduled to start? Or should I wait till the 29th, and start it then?
