An old girlfriend of mine has recently come to me and said that she was pregnant, and that the baby was mine. I really don’t believe this is the case since I broke up with her because I caught her cheating on me. There is at least a decent chance that the baby belongs to someone else. I want to get a paternity test done before I agree to anything. Where can I get a DNA paternity test done, and how expensive is it? If it is my baby I would definitely like to be involved in its life, even if it does mean dealing with my ex.
