Note that a blackhole with event horizon radius less than 1 mm would be a little bit more massive than the earth. If it is moving slowly enough, it would “capture” you in a tug of war with the earth. If it wasnt for earth I think you would end with it in your center of mass but given the earth, I think higher in your body.
