You can take Tylenol cold and flu. Also warm honey lemon water is great and chicken noodle soup
The safest thing is benadryl. It ***** but in the first trimester you have to just stick it out and be sick unless your doctor tells you other wise. Hot showers help clear a stuffy nose. Increase your fluid intake and take Tylenol for a fever. Also, rest rest rest. Our bodies dont fight off infection like they did pre-pregnancy! If you get a high fever get in touch with a doctor or emergency room.
