TMI!

Hey ladies quick question I am 7dpo today well yesterday morning when I peed there was some blood in my urine not a lot but enough that it tinged it pink and the same later in the afternoon. But there was nothing when I wipe and today nothing my urine is a normal color. It was very strange to me is it possible if implantation bleeding is so minimal it will come out when you pee and you might not get any blood when you wipe? I know it’s a stupid question but I never had implantation bleeding before with my other 2 pregnancies so I don’t know what to look for
