What’s everyone doing to help with congestion? Im sick right before baby comes.

Hey everyone. I’m 36 weeks and on top of having insomnia I now have a chest cold with severe congestion. I had a bad cough but I think it’s slowly getting better. I read that congestion is common in third trimester but I can’t breathe when laying down and it’s really impacting the little sleep I get. I know we can’t really take meds when preggo so what is everyone doing to help with their congestion? I’ve been taking hot showers and trying to inhale steam but it’s not really doing anything. Wahhh. SOS.
