Wow that is odd they didn't ask you beforehand? Did she just tell you she was checking your cervix? Sometimes they will do that but usually tell you they might do the 'sweep' of the membranes at the same time. She didn't stretch you to 2 cms - the stretch part doesn't really do that but if your card says you are 2 cms already, it means all the prelabour you have had is doing what your body needs to do! FWIW I had 3 s&s's with my last one when I was 3 cms dilated, and other than a few ctx's I never went into labour. Just remember bub will come when he/she is ready.
