So yesterday I was supposed too start my period and it never came today but when I went pee this afternoon I wiped and there was this like light light pink blood after I wiped. Can this be implantation bleeding. I am not bleeding at all and it comes and goes it's been like that all day. And I've been throwing up everything I eat for the past two days. Should I take a pregnancy test early in the morning
