i am a 20 year old female dating a 17 year old female. her parents did not know but recently found out can i get arrested or charged with anything?

The current age of consent in Georgia is 16.  Assuming you had no sexual relations with your girlfriend before she was 16 (if you had relations with her in other states, you may have to check the age of consent in those jurisdictions) and that she is not otherwise impaired, you should have no criminal liability.
