My period is exactly a week late and today I just went to pee and I saw super super light pink when I wiped, barley anything at all. I do have cramps also. Could this be the start of my period or is it pregnancy? Any advice? I took a pregnancy test yesterday in the afternoon, but if had peed several times that day so my urine was kind of diluted. It was negative. I might have seen a very very faint line but it could have been my eyes tricking me.
