Oh, throat pain can be so annoying, especially when you can't take normal medicines. It isn't a typical pregnancy symptom, but our immunity does go down, making us catch colds easily. Take care, dear, and drink some warm ginger water.
Throat pain is usually not a direct sign of pregnancy, it might be due to weather or infection. But since you are expecting, you should get a routine thyroid checkup done too as recommended by your gynac because thyroid issues also cause throat discomfort.
Normally, throat pain is just a sign of a mild cold or acidity. When I was pregnant, acidity sometimes caused a burning throat pain in the mornings. Drink warm water and see if it gets better.
I just had my baby recently, and I remember having throat pain in early pregnancy because of acid reflux! I used to do salt water gargles and keep a check. But check with your doctor if it's accompanied by fever.
