It is important to first lower the fever, as it can be harmful to the baby. Tylenol or a generic brand is a good choice for this. You can take X-Fort, which is 2 tablets of 500mg every 4 to 6 hours if needed, for a maximum of 8 tablets per day. It is also recommended to dress lightly, use a warm damp cloth on your body, and drink plenty of water to help reduce your temperature. The Tylenol will also help relieve your body aches and headaches. Using a saline solution like Hydrasense or Sinus Rinse is a good option during pregnancy, using it minimally in the morning and evening, up to 3 to 4 times a day. As a second option, you can use a nasal decongestant spray like Dristan or Otrivin, one spray in each nostril up to 2 times a day in the morning and evening if needed, for a maximum of 3 to 5 days. Apply it after using the saline solution. Hope this helps and feel free to ask if you need more information. Thank you and take care!
