Hi. I'm 16 years old and I've been on the nuvaring for about a year and a Hal now. Last month I took the ring out when I was supposed to and I got my period when expected. But, it only lasted two days, which isn't normal for me. I chose not to put the ring back in & had unprotected sex two weeks after I got my period. Now my period is due, but it is no where to be seen. Am I pregnant?
