I would call your doctor. It can get much worse and you may need to be put on an antibiotic. I was told to not take any hot baths at all. Everyone is different so call your doctor. Hope you feel better.
You can take robitussin!? I wish someone had informed me on this when I felt like I was in my death bed last week. LOL.
Anywhooo, take warm baths, drink tea with honey and lemon. Tylenol. Get the nasal saline spray. And get lots of rest. Feel better :)
Robitussin is safe to take x
Hots baths with a bit of steam inhalation, rest and fluids. I know it's rough being ill when your pregnant, hopefully you'll get better soon x
