Confused as ever

Marleny

Ok I need help to understand this

So yesterday I was bleeding a light pink color

So today I woke up with a light brown color

ANd I also used the bathroom and nothing there

But when wiping it's a pink with little brown

So me and my partner was talking about

This and he said if I was pregnant he will feel it

But mind You I been cramping none stop

Someone explain this to me
