Please help.

I woke up this morning and feel that my pad is full and my blood is dripping af. So I quickly but gently search for my bigger pad to change. Then bam. I'm bleeding too much there's blood on the floor. Is this normal?

I had sex on june 20 (3 times) then I done it yesterday again, we tried having sex with my period but it's hard for us, so he just thrust it in a few times and that's it. There's really a lot of blood clot.
