The normal statute of limitations for a felony is 3 years from the date of offense. However, there can be circumstances that can impact that. My expectation is that you would have been charged a long time ago if the DA intended to do so. So, I would contact a family law attorney here to file a Petition for Allocation of Parenting Responsibilities and Child Support and who also knows criminal defense law. Many of us offer either free or discounted initial consultations.

Felony sex assault on a child has no statute of limitations. Misdemeanor sex assault has a limitation period of 6 years. However, if the father was 17 when you had consensual sex then it is not a crime in Colorado unless you were in a position of trust (such as a guardian, teacher, coach, etc) or closely related to him.
