what to do with this cough?!😞

I'm 33 weeks nd 4 days nd this cough has been going on for almost a week now. Keeps me up at night nd I know this is a little tmi but I also cough out mucus too. I have went to the doctor nd they just say like always, it's just a virus going around nd didn't do much. I'm just being a worried mama nd hoping my baby is ok when I cough nd want to know what can I do to get rid of this. Nd also my baby shower is the weekend! Any remedies anybody? Please nd thank you!
