Well I had sinus and cold like symptoms when I was pregnant with all three of my girls, but not my 2 boys. Infact it was so bad I was on antibiotics all 3 times only to find out 2 weeks later that I was 8 weeks pregnant each time. Prior to this home tests showed negative. There was an absence of fever though, just the pain, runny nose, stiff neck and horrible discomfort in that region that lasted a week and a half even affecting my teeth an seeming to come out of nowhere. So I think we are all different and I'd say trust your instincts and also check in with doctor.
