It's possible for your premium to increase because insurance companies don't like paying money, at-fault or not.
A buddy of mine was in a similar situation, from the other end. Got in an accident the same day he bought the car. Luckily the other guy let him settle privately. At the same time, if damage is minimal, it could actually be cheaper in the long run for both parties to settle it privately.
Reporting the accident is the "right" thing to do, but like some people have mentioned, it may be too late already, and your insurance company may not be willing to wait to go after her.
