I'm 17 and so afraid of pregnancy! Am I pregnant?

Okay so me and my boyfriend were rubbing, but there was no penetration, he had underwear and I did not, and no ejaculation. This was two weeks ago. A week ago I had a tiny spot of blood on my underwear which terrified me. This week I have had egg white cervical mucus which is now drying up so idk if it's ovulation or a pregnancy symptom. So far I have had no symptoms of pregnancy except I am pretty tired, but not overly tired. I also have no idea if I missed a period because I usually go 2-3 months without one. I think the spot of blood scared me the most. Please be nice, I know I am too young for this:( do you think I am pregnant??
