Ventura County Court House

Need some help in California Ventura County??

Im 22 my girlfriend is 17 and will turn 18 in FEB and she is pregnant and our baby is due in mid FEB. The law below indicates that a 21yr old that engages unlawful sexual act to a 16yr old or minor is guilty of a misdemeanor or a felony. Dose the court house or district attorney still show intrest in a 17 year old who is about to turn 18 and is with a 22 year old adult. I talked to a mediation center and while talking to them the called sevral people, police station, Attornys, District Attorney office. and investigations and some said that they would probbaly file the complaint and it probably wouldnt be taken any action to it . what do you think would happen?
d) Any person 21 years of age or older who engages in an act of unlawful sexual intercourse with a minor who is under 16 years of age is guilty of either a misdemeanor or a felony, and shall be punished by imprisonment in a county jail not exceeding one year, or by imprisonment in the state prison for two, three, or four year

First of all, this is only an issue if your girlfriend makes it one, or her parent do. If neither of you make it an issue, then it is not one. Who would report it?
