Is there ANY CHANCE I could be pregnant from this?!

Hi guys. So, a couple of days ago my boyfriend and I got heated. We were in bed making out. We then proceeded to take off our clothes. I put a condom on him because we basically did oral. I didn't want to get any STD if he had any (which I doubt, but you never know). 
The condom NEVER came off, I didn't want to risk anything. Then he started fingering me. That lead to him eating me out-- we basically had oral sex. No intercourse occurred, but I am still frightened that there could be a possibility of pregnancy. Please help!
