Thick Light-Pink Discharge - HELP

AF is due tomorrow (12/17) and I have had no signs or symptoms of her coming (I usually feel it). Just now I went to the bathroom and had a good amount of really thick lightly pink tinted discharge and that has NEVER happened to me. Has anyone else ever had this happen and gotten a BFP?! There are cases where I have spotted before my period but never the discharge like this..... opinions/advice please!!
