Help please

Devon

I am 8 days late. I took 2 pregnancy test on the day I was late and the other a few days ago both were BFN. I have alot of symptoms such us tender breast, extreme fatigue, frequent urination, nauseous almost all the time. I also have excess white discharge it's not clumpy or has an odor. sorry if that was TMI. Could I still be pregnant or could something else be happening?
