Bleeding after sex

Ok so I just got married about a month ago and we were both still virgins, it hurt like a bitch for me but I’ve been getting more used to it and have started enjoying it a lot more, The problem is I think he’s to big for me 😬 he’s about 8 inches long and I can only fit like 7... and when we try’s to go deeper then that It hurts really bad! A friend told me it’s probably my cervix but I’ve noticed that whenever he does hit it I bleed a little bit.... is that normal? Does anyone else have this problem?
