To relieve congestion in your nose and prevent it from running so much while pregnant, you can try using nasal saline solutions like Hydrasense or Sinus Rinse. These can be used as often as needed throughout the day and at least 30 minutes before going to bed. You can also try throat lozenges like Halls or Fisherman's Friend to soothe any throat irritation, in addition to taking Tylenol. Drinking plenty of fluids, whether cold or hot, can also be helpful. If your symptoms persist for more than 7 days without improvement, it's best to consult a healthcare professional for further guidance.
