Father sexually assaulted child

I’m so confused and cloudy. I really need advice. When I was little, around 4-5 my father would take me from my room at night and make me sleep with him. He was not clothed. I remember feeling gross, dirty, and scared. When I was older I found child porn on his computer. Now that I’m much older, living with my husband and trying for kids, I’m having trouble believing myself. It’s like I don’t trust my own memories. I want to cut him out of my life but I get worried and start questioning myself, what if I’m wrong? What if what I’m remembering isn’t what really happened? What if I destroy the entire family for nothing? Has anyone else gone through this?

EDIT: my mom passed away during childbirth.
