Same happened to me yesterday, I had a cup of hot water with a tablespoon of honey and before bed two paracetamols, feeling a LOT better today! :)
Drink alot of hot tea and keep hydrated until you speech with your doctor. There's a lot of medicine us pregnant women can't take
You could try Tylenol, Benadryl, or Robitussin DM. Maybe try some soup to help as well. Hope you feel better (:
