Well I am going threw the same thing, And So far it sounds like Implantation Bleeding alot of women are going threw it now. It is not no were near pink if people know there colors right it is actually light red. It is not a menstruel at all. It can have a tiny bit of small red clots in the beginning and can occur before or during the time you would menstruate.
PS: implantation bleeding will be very light pinkish colour .It doesn't neccesarily have to occur inorder to approve very early pregnancy sign.
Hardly some women do mesurate when they are pregnant.I now have forgot the term.
take a test to assure yourself.
If you are pregnant, you won't have your period.... I think that's all I can say!
