Cold symptoms a sign of pregnancy?

Heather

Hi! I read recently that it can be possible for cold symptoms to be a possible sign of pregnancy. I’ve been having some weird head cold with no fever, aches or chills but runny nose and congestion. Had two mornings on days 8 and 9 dpo with waves of nausea and took a test on day 10 that was BFN. Have about 3.5 days left until AF. Have had some light cramping today too. Has anyone else experienced this and then found out you were pregnant?
