I m 31 weeks pregnant and I have gotten many viruses throughout this pregnancy. My most recent infection followed a Tdap shot I got last Thursday. I ve had a dry cough, sore throat, cankersores in my mouth that are very painful, and nasal congestion (clear, bloody mucus when I blow my nose) since last Friday. I started to feel better a couple days ago, but now my cough has gotten worse. It is dry, persistent, painful, and I taste a little blood when I cough. No chills/fever, just this cough that is very painful.
