Tmi? But scared

So today I had my first appt, they did a pap and I started bleeding. Like a lot. It’s been an hour and I’m still bleeding. I’ve had a previous miscarriage. No cramping and after the pap I did have a vaginal ultrasound and everything looked good heart beat and all. I just don’t know they said I maybe have uti or something but I never had this happen when I was pregnant with my daughter. Should I be scared?
