We had sex without a condom but I didn't ejacuated inside her. Can precum make her pregnant?

Yes.

Yes, it can.

Yes it is possible.

Are you ready to be a daddy yet... the chances are greater than winning a raffle are.

Don't do out in the rain without a raincoat or Umbrella unless you want to get wet... don't have sex without protection unless you want to be a parent (and even then its not 100% effective).
