Weird!

I'm in my TWW and my smell has heightened so much! The smells that I smell while riding in the car, kill me and nobody around me smells what I smell, I feel crazy af but HONESTLY, I do NOT think I'm pregnant ..... I just think I'm off right now because the smell thing is tripping me out. AF Is due on the 4th, so I'm just waiting on it to show up. What are y'all thoughts on my situation? Early signs? Or am I just tripping.
