Symptoms but no BFP

Tara
AF is due to start tomorrow but I've already taken a couple tests because I'm having crazy symptoms 
-a lot of white discharge 
-fatigue 
-nausea 
-allergies for like 2 days which I didn't even know was a symptom 
-shortness of breath 
-headaches everyday 
-my legs and ankles swell after being at work too long 
But the only pain in my breasts has been a really short mild shooting through the right one 
Did anyone experience anything like this?
