Am I pregnant ?

Chantelle • I'm 22, my partner is 23. Ttc baby #1 can't wait for our little miracle, follow me or add me on Facebook and we can support eachother :)
I haven't done a test yet, my period is meant to start today, this morning when I wiped sorry for tmi but there was a small amount of light yellow tinged cm on the tissue, didn't think nothing of it so did a cervix check and  there was abit of blood on me fingers. Now it's light brown? Does this mean AF is getting ready to come or?
