Hello, I Am 8 Days Late And Have Clear Discharge

hello, i am 8 days late and have clear discharge instead of my period. Also i am having lower back pains for two weeks now and my appetite has increased but have dry mouth alot. Dont know if its because the stress from work or my sleeping schedule but also been exhausted to the point that if i lay on the couch then i can easily fall asleep. Am i pregnant?
