Is It Possible For A Woman To Get Pregnant From Semen Exposure On Her Fingers After Non-penetrative Contact?

Hi, I am a male who had an unwanted sexual encounter 2 months ago. I was travelling on business. A hotel maid walked in to the bathroom on me and started giving me oral sex. I asked her to stop and she continued. I finally got her away. As she was leaving I ejaculated. I remember covering the ejaculation and I am almost sure she left. However, there is a slight fear in the back of my mind that she stuck her finger in and took a bit sperm before leaving. (I don t think this happened but it is a traumatizing experience and i am not 100% sure). For the past 10 weeks,I have lived in fear that she took that drop of sperm out of the hotel room and went to a private place to insert it and impregnate herself. I know this is irrational but it is driving me crazy. I have been told that pregnancy is not possible in this situation,yet I read online that it can technically happen Can any ob/gyn reassure me that a woman can t become pregnant like that?
