Wtf is wrong with me ???'

Ok this has happened ever since I got my period. When I'm own my period I don't pee blood i just normally start to see blood when I'm done peeing.And I can clearly see blood on my pads so how come I'm not seeing a toilet full of blood ? Lmao I'm only 12 and my mom passed away so I'm not sure how this whole stuff works but plz help me 😩
