Bleeding after a pap smear

I will be 9 weeks tomorrow. I went in for my initial ob appointment yesterday and the dr did a routine pap smear. I started bleeding so he put silver nitrate in my cervix and got it to stop. I started spotting through the night so I went back in today and he did the silver nitrate again but now I'm bleeding worse than I was before I went in. He said that there wasn't anything else that he could do so we just had to pray that it will stop on it's own. Ultrasound showed baby is still doing great, heart rate of 171, cervix was long and closed. I was just wondering if anyone else has had this happen?
