possibly pregnant???

Hey y'all. so my period is due today but there is no sign of it coming besides sore boobs which could be either period or pregnancy but I am absolutely exhausted and I have just had tons of discharge or cm or whatever, even more than when I ovulate! ive constantly been feeling warm and wet down there sorry for the tmi. has anyone had this happen and been pregnant? I had the smallest bit of light pink spotting yesterday.
