Bleeding for 4 days after sex

(I know i’m posting here way too much lol but i literally have no one to talk to about these kinda things)

So i lost my virginity around a month ago and still i bleed almost everytime we have sex but this time it was worse. I bled during the sex and then i’ve been bleeding for 4 days so i’m even using a pad. Why does this happen? I feel like i might have a problem bc this time it hurt so bad at first again so he had to hold me in a position in which i couldn’t move at all so i couldn’t push him away bc it hurt so bad. He actually did it before too but the first time he did it, it still continued to hurt when it went it for a few minutes. But this time it stopped hurting a few seconds after he put it in. But then in doggy i started bleeding but i wasn’t in any pain at all. Is it normal to bleed for 4 days? Could the fact that it hurts be related to this? I mean we do have foreplay, he goes down on me everytime before piv and he uses lube too. I can’t go to the doctor for now.
