Late by 8 days

Hiiii, so I’m 8 days late and have not been cramping at all. I also have the milky stretchy discharge. What’s the chances of me being pregnant? I’m too nervous that if I take a test, it’ll be negative. I’ve been sexually active and I’m not on any birth control. Also, this morning stopped by McDonalds and got some food. On the way back home, the smell was so intense, I got super nauseous. Idk everything is just weird for this cycle. It could be in my head I guess.
