If you truly care about your girlfriend, than what she has done in her past shouldn't matter. Tell her how you feel about it and maybe that will make you feel a little better about the situation because you have gotten it off your chest. Be thankful that she trusts you enough to talk to you about her past relationships because usually that can be very difficult.
The only way to know for sure is to ask her.
If you care about her then nothing. She told you the truth and you should appreciate her honesty, even if it was belated.
