Flu/cold symptoms

I was just wondering if anyone has ever experienced flu/cold symptoms before they got a Bfp? My period is a week late but I am terrified to take a test because I don't want to be let down again. Maybe I am just reading into every little thing hoping that this month is the big one. But my nose this morning is really runny and I feel like I have a sinus headache. I read that your mucus membranes swell sometimes in early pregnancy.
