It's very simple:
You cannot become pregnant from a finger.
You can only - ONLY - become pregnant from semen entering your vagina.
So: if a finger entered your vagina, carrying semen, then, yes, you could become pregnant.
BUT: it would be the semen that made you pregnant, and not the finger.
No-one can tell you how likely this is to happen.
So make your bf wash his hands before sexual activity.
That's it.
