Try rubbing vicks vapor rub on your feet before bed and covering with socks. I consulted my doctor and this is safe or even just rubbing vicks on your back and chest. It seems to help with congestion.
Tylenol! Don't take ibuprofen!!!! It can make your baby breath air in the womb which everyone knows is full of amniotic fluid. So it could drown the baby. Other than that try saline spray
Ask your doc what meds are safe. I was actually using saline spray..just squeeze it up your nose. It loosens a everything up and I swear it made my cold go away quicker. I just taking meds while pregnant!
