Scared

Last Monday (11/06/17) was when my period finished. I had started birth control on the day before. I gave oral to my boyfriend and when he finished I spit out the ejaculate and waited a few minutes (wiped off my face, etc.). Then he french kissed me and after a minute decided to give me oral. It was not even 30 seconds before I told him to stop because I realized I could have transferred sperm and that could be bad (possibly?). That day I had my Well Woman's exam and I told the doctor my story. She said I couldn't get pregnant but I still feel uneasy. Since 11/11/17 I've been spotting (so three days now). I'm extremely worried that this is the first sign of pregnancy, or implantation bleeding. I'll have to wait another 3 weeks or so to take an accurate test but I guess I just need help with more experienced people. I also have an appointment with a counselor this week because of my terrible anxiety. Please don't be mean, I'm scared enough as is. I have so much going for me and I can't let this stop me from moving forward.
