Sinusitis at 39 weeks

Domo

I have been fighting a nasty sinus infection for 11 days now. My dr just prescribed me a nasal spray yesterday (Tuesday).. I literally can't breath through my nose and my face and head hurt so much... am I able to take a Tylenol Cold and Sinus at 39 weeks pregnant? Ive tried so many things to try and relieve my congestion, but nothing is helping. I'm terrified of feeling like this when I go into labor... 😭
