I’m in a crisis

I just recently been thinking about this. Parent’s are 9 year apart. My mom gave birth to me when she was 15 and they’re still together. Is my dad a pedophile..??? I don’t know what to do, do I confront them?? I don’t believe my dad was interested it other women though, but my dad was in collage and my mom was 14 when they met........I-I don’t know how to react to this
