ok i am 19 and me and my girlfriend have been having unprotected sex for the past 3 weeks. she just got the nuva ring last month and that is the first birth control she has been on and she was supposed to put a new ring in on friday and her mom is getting her on the depo provera shot and i was wondering if her using the ring for too long would make it where she will get pregnant or not. she says it is fine but i am about to deploy and would like to be here if she could be pregnant. any help is greatly appreciated
