It is not uncommon to experience symptoms like a sore throat, stuffy nose, and sneezing during pregnancy due to hormonal changes and increased blood flow. These symptoms are usually caused by nasal congestion or allergies. However, if you have a history of multiple miscarriages, it's understandable that you may be concerned about any new symptoms. While these symptoms are generally harmless, it's always best to consult your healthcare provider for reassurance and guidance specific to your situation. They can evaluate your symptoms in the context of your medical history and provide appropriate advice or treatment if necessary. Remember to take care of yourself physically and emotionally during this time, as stress can also impact pregnancy outcomes.
