Am I pregnant?

Patient: I’m not looking to get judged for this because I know it was wrong and I’m a teen but I had given a blowjob to my boyfriend. I may or may not have had cum on my hand. But once again this sounds dumb but there was no toilet paper in the bathroom so I used my hand then washed it. I wasn’t thinking that I could have had cum on them. I am on my period and had a tampon in as well. Is there any chance I could be pregnant? I don’t know if I’m freaking myself out or not but I’m terrified.
