Is it okay for you to have heavy cough in the first trimester of pregnancy?

Your immune system does not run at its usual best when you are pregnant because your immune system is busy protecting your developing baby. So it's perfectly normal to fall sick. Your body can't fight off colds as well as it normally does, making you more vulnerable than usual to the stuffy nose, coughs and sore throats. Eat healthy, drink lots of water, get ample rest and load up on vitamin-c laden foods -- to ward that cough and other flu symptoms away. If you need to take medication, best to check with your doctor which kinds are safe.
