You are only 21 so don't get too worried about it! Most dr's suggest you get one when you become sexually active. I haven't heard of dr's giving pregnant woman a pap smear, it has never been a question that I've been asked when pregnant. It's nothing to worry about, dr's are used to doing them and after years of med school it will just be another pap smear, if you would feel more comfortable going to a dr that does them every day rather than a GP find a gynecologist.
