Medicine advice PLEASE

Okay, so I’m 21 weeks and have NO IDEA what to do/take for this cold/death plague I’m currently experiencing. It’s gone from a slight cough to feeling like razor blades in my chest when I drink water in a matter of hours. It woke me up from a dead sleep just trying to breathe. Since my medicine choices are extremely limited, can anyone please recommend something for relief?

I had a fever yesterday, but took some Tylenol and that’s pretty much nonexistent now, just a half clogged half runny nose, painful chest, and phlegmy/mucousy cough. Please help!
