Should I be worried?

This might sound stupid... need help. My mind is very OCD.

So my period is 2 weeks late and I gave my boyfriend oral sex last night. He came in my hands and I just used baby wipes to clean them because I was no where near a sink so I couldn’t wash my hands with soap and water.

I came home and went to bed and when I woke up and my hands were inside my underwear (sometimes I scratch my self when I sleep I know it sounds weird) and then I remembered that I didn’t wash my hands last night. 😳

Can anybody get pregnant like that? Should I be worried?
