Blood after the first time sex

Hello good morning 💓yesterday I tried to have sex for the first time but unfortunately two things happened.

1. He did not fit and when he tried to push it in it hurt like hellll and burned a bit. I think I was turned on enough but i am not sure.

2. This morning, I went to the toilet and my panties were full of blood. I should start my period soon but it’s another type of blood.

Can some of you explain why these two things happened ? 💆🏽‍♀️🙂‍↕️ thank you very much 🥰
