Pinkish milky discharge

So yesterday morning I woke up and went to pee and when I wiped I have pinkish milky thick dishcharge I've never had it happen so I thought it was the start of my period since I've been cramping lately and had sore boobs like CRAZY!!! I put a tampon in and when I took it out nothing but more of the discharge was on there... and today it's gone..  my period isn't due till the 29-30th I've been cramping off and on. I read online it's a sign of pregnancy but like they say don't ever google symptoms cause they give wrong answers. Anyone had this happen? Help...
