Can I get pregnant if...?

Around the 26th of march, my boyfriend and I participated in our first sexual acts together. I gave him a blow job and he fingered me. But it was more of me licking him and him giving himself a hand job in between. He got off first and then around 10-20 minutes later he started to finger me without washing his hands. I know that the sperm should've dried out or been wiped off his hands by that point. But then a couple weeks later, he "ate" me out. This was after I had gotten him off only a few minutes earlier. He did ejaculate in my mouth, I spit it out and then we kissed a little bit later. Before he started to actually lick me, he wiped his tongue onto my jeans which were still on. Is it possible that somehow some of his sperm was transferred to his mouth and then into me? I'm only two days late, but it doesn't change the fact that I'm worried. I've had some PMS cramps and bloating, but nothing like I normally get. I also have a lot of clear discharge but no blood yet.
