Hello everyone I don't normal do this but I've had a sinus infection since before Christmas. My OB Doctor put me on antibiotics for a week which I think if I were on longer it would've helped more. Now I got a new job which mean new insurance, I had to switch OB practices. My sinus infection is turning into a cold and sore throat. At my last appointment I was told my blood pressure been great. However, I'm a little nervous to take anything just because I know that can change toward the end of your pregnancy. Do any of you have advice? I have a sore throat, running nose and cough.
