You are not pregnant yet. It takes several days for that to happen.
If your period is about two weeks away that could mean that day was a fertile day (more data needed!). The concern must be whether it was semen or pre-cum (don't you know?). Statistically, there is less chance with pre-cum of getting pregnant (some men do not have sperm in their pre-cum) unless he had ejaculated recently since last urinating. But it only takes one sperm! Concerning how far his fingers went in, halfway could be plenty far enough if sperm were on them. But if it were just pre-cum, and his hands were dry for over half an hour before insertion, the chances are very low.
Are you a virgin with an intact hymen? Did he get past that? Were you wet? All these things make a difference. The possibility of potential pregnancy cannot be ruled out completely from the brief details you have given, but the chance doesn't appear to be high.
I hope this helps a bit. Take care.
