Bleeding after sex 4 weeks after birth

So last night me and my BD/BF decided to have sex. I had my baby 4 weeks on this Sunday coming up. We did it rough and we also did this morning before he went to work because he’s been patiently waiting and I feel so bad for him waiting so long. But yes it hurt at first but he worked his magic and it stopped hurting. I’m was still lightly bleeding from when I gave birth and just now I went to the bathroom and my pad was full of blood! Idk if that’s bad or not.. I feel it is 😂😂
