Please help?! 19dpo

angela

I am 19dpo and I took a dollar store pregnancy test last night but it came back negative. I did bleed a day before my period but it wasnt normal. It was pink and very watery.. now still continuing I am having VERY THICK EGG WHITE CM! I have never had this after a period and my cervix is extremely high. What could this be?! And should I retest or assume it was AF?!
