All the symptoms but a negative.

As of today I am on day 40 of my cycle, I generally only have 33 days average (can be a few days before or after) considering this I am officially late for my period and have been getting all of the symptoms of pregnancy/PMS (Sore breasts, fatigue, not hungry which is rare because I'm always eating and a yellowish discharge), I have taken two pregnancy tests within the last few days and not even a faint second line just a straight up negative. 
I'm going to wait a few more days before seeing a doctor but is it possible I'm pregnant? I've never had a discharge like this before which makes me think I am. Also we have been only using condoms during sex for protection.
