Are flu like symptoms such as body aches and aching eyes symptoms of pregnancy because you have heard flu like symptoms can happen in pregnancy?

You may have body aches but aching eyes would not be a typical symptom of pregnancy. Usually when it is said that you might have flu-like symptoms with pregnancy, it is referring more to the malaise, unexplained fatigue, and nausea and vomiting (such as with "stomach flu"), not the upper respiratory symptoms like cough, sneeze, sore throat, runny nose, watery eyes and high fever.
