Did he feel pain?

I read something I probably shouldn’t have read and now my mind is going to the worst thoughts possible. My baby was fully developed he was born 33 weeks and passed at 33 weeks due to his cord wrapping while getting into position. Now I’m thinking “did he cry? Did he feel pain? Was he mad that I didn’t help him in time? What was his last thought? Did he hear me the night before losing him when I said my final I love you while he was breathing? Does he still hear me?” I’m so unhappy with these thoughts and I need someone to help me understand 💔
