My sister recommend sipping on apple cider vinegar or humidifier or a warm shower with out the fan on. I saw the pharmacist today and she gave me kids stodal its homeopathic medicine safe for expectant mothers.
I use essential oils in a diffuser to stop a cough. I had HORRIBLE allergies for most of my pregnancy so I actually carried the bottle in my purse and would pull it out when I couldn't stop coughing at work. I use the Breathe Easier blend by Eden's Gardens, and yes, I got the ok from my MW. :-)
