Pap smear

Ok so today I had my annual Pap smear, right after I finished the exam it felt like it hurt down in my vagina and when I went to restroom there was red tinged discharge on my liner. My husband insisted that we be intimate and well since I am on my fertile days and trying to conceive I gave in, although it was feeling uncomfortable down there. After being intimate we both noticed quite a bit of blood and I'm freaking out because I had never bled after a Pap smear, but then again I had never had sex that same day after the exam....(keep I mind i started my period on Sunday 23 and finished on 26.... ) any ideas of why the bleeding?
