What Are The Chances Of Pregnancy Through Non-penetrative Sexual Activity?

My boyfriend and I were fooling around one day. He went to the bathroom to take care of himself, but didn t get anything on his hands, washed his hands, wiped them, and used hand sanitizer and wiped them again before he touched me. We didn t have sex, but he did use his fingers on me. I got a little freaked out by this and decided to check my cervix (I don t why but I did) and it s been high and open for a while. I keep freaking myself out. I haven t gotten a period for a year and a half so there s no use in waiting for that (not from this, from stress due to other goings on) and I keep stressing myself out. I knew it s probably unlikely that I am, but can you please help call my nerves? It s been about 2-3 weeks since the incident and I m still losing my mind.
