Yikes- he fingered me?

I know this is going to sound like all of the uneducated "Am I pregnant?" posts on this app, but please humor me and read to the end. Yesterday, my boyfriend and I were masturbating next to each other. He ejaculated (and a bit got on his hand), and then wiped off the two fingers he had gotten semen on. He says that his hands were dry and said that only a drop (now dry anyway) was originally on his middle finger, which he then fingered me with. I figured the chances of me getting pregnant aren't high, but I want to see what you lovely ladies think.  This event was also 1 day before my ovulation began.
