Pap vs. Vaginal Exam

[justreadmyspine.livejournal.com]

Last week I went to the doctor because I was having really big clots during my period (which shouldn't even have happened because I'm on the patch and currently had one on). I'd never had any sort of vaginal exam (which they thought was odd because I've been on HBC for over three years, but whatever). They said they were going to give me a vaginal exam, but not a pap. What exactly is the difference? Thanks!
