What does it mean to have your period nonstop? Am i pregnant?

I have discharge all the time. Sometimes it'll be clear long and stringy, white, or like rubber.. I started my period, at first it was really dark..then it turned bright red. I was on it for two days straight. I woke up this morning an didnt have any blood on the pad.. Now im spotting. What is this? My last period i had it for like 3weeks..on an off.. Spotting.dark. Brown discharge. Please, somebody tell me who already knows not what ifs. Im not on birthcontrol..i used to have sex everyday but now i cant cause my boyfriend thinks its best for me to figure out whats wrong first...ive used two pregnancy tests an they were both negative..Everytime im done going pee i see white stuff in thedrips of my pee. Todays a bew day an im adding stuff right now from today i woke up this morning an wasnt bleeding everytime i go pee i see thos white stuff dripping.
