Confused

I have been married for about 9 months. We have less than 2 years of history with my spouse, but we see each other as our soul mate. We are both grateful for our constant presence. I think she is my biggest chance.
Besides all this, I made a mistake. One night while my wife was asleep, I opened an Instagram link on my own pc, first thinking that it was my own account, and then I saw that it was my wife's account. Since I am not very knowledgeable about Instagram, I clicked on the icons above to see what works. One of them was direct messages, I did not read it, just looked and when I went down I saw the correspondence with her ex-boyfriend somewhere below. She told me about that man. She said that he was a psychopathic personality and that she had a hard time getting rid of him. When I saw him, this came to my mind and I got angry and looked at how disturbed this psychopath was my wife. On my way up, I saw nude photos of them alone and having sex together, taken 4-5 years ago. I had a great shock for a moment. My hands started to tremble. I spent the whole night without sleep.
This is something that happened before our relationship, so I am not angry with my wife. But those images do not go out of my sight. I often get teary-eyed. I cannot say anything to my wife. I don't want to embarrass or offend her. I don't want this to hurt our relationship. However, I do not know how to get over it.
I don't know if I talk to her, will it affect us negatively or it will be worse if I don't talk. I'm so confused.
I don't know if anyone with an opinion can help me.
I think there are things I don't know much about right now.
