Can I get pregnant this way?

I gave my BF a blowjob and I tried to swallow but ended up spitting most of it out...then he fingered me and after I was done I went to the bathroom and washed my hands but realized that my cervix was hurting. This was about 6-7 minutes after the blowjob. 
I sucked my finger once and tried to reach up there, only to realize in horror that I might still have semen in my mouth, thus in my saliva?? 
Can I get pregnant this way? I'm really scared.
