I need help! Need advice!! No bad comments please....

Hi there ladies. I'm kinda confused. It all started on November the 25 that's when my period started. And it lasted for 8 days. And on December the 27 it started but lasted 1 day. And this month of January it hasn't come at all. I only have a lot of monster white discharge and weating my undies. Only my lower back has been hurting a lot And feel bloated. Have you any ladies had this before and be pregnant or it was something else?
