Is it possible to get pregnant if he fingered me with pre?

I'm not sure if I was ovulating, but I think I was because I had mucus discharge. I follow a 28 day cycle. My last period started on the 9th last month. He fingered me on the 29th, two days ago. There was no / involved. I was giving him a bl ow job and a , he might have or might not have had pre, i'm not sure. But I spat my saliva after I regretted doing it. Just right after I blowed him for like not even a minute. He put his fingers in my mouth and my mouth might have had his pre. Then he fingered me. Like halfway, his whole finger didnt go in. He told me that the finger he had in me wasn't in my mouth but he rubbed me with two fingers, one which had been in my mouth. I'm having a little cramps, which I usually get before my period. And I dont have a fixed period date. Am I pregnant? I'm so stressed out over this and its driving me crazy. I told him that I would not do anything ual anymore until I'm ready to be pregnant. He agreed.
