Bleeding after sex

Hey I need some help

so I had sex with my boo yesterday and after I had a spot of blood and he asked if I was on my period and I said no, because my period just came 2 weeks ago. So when I went home I put a pad on to sleep and I checked it this morning to shower and it’s soaked with blood!! What happened? Is this my period again? Did he hurt me during sex or something?

* btw This wasn’t my first time having sex, but I haven’t had sex in a while so it was tight*

Bleeding after sex has happened before but only a few drops, not my whole pad soaked
