Bad cough

I might’ve gotten a cold and I’ve had a very bad cough going on 8 days with it. Ugh. I’m 18 weeks and there’s so much controversy about taking mucinex DM my dr office is closed and I’ve googled everything possible and everyone is saying hot teas , hot water/salt, vicks on feet, I’ve taken robitussin nothing has helped. I’m desperate this cough doesn’t go away at all
