Bleeding after masturbating normal?

laiiid

Hello everyone, I just found out that I’m pregnant. According to the doctors I’m 5w & 5days. I had sex with my partner and after I noticed he had blood on him ( this was during implantation )

Now today I decided I wanted to have fun with myself and after I was done I went to the bathroom when I wiped I saw blood. Why does this happen? Mind you this is my first pregnancy
