Any advice for dealing with a cold while pregnant?

I’m 24 weeks tomorrow and I’ve been sick all week with a nasty cold. I called in sick Monday, had Tuesday off work because it was my birthday and I had a final exam (I’m an online university student), called in again Wednesday and went to the doctor and got a doctors note excusing my absence Monday through Thursday. I went back to work today and was sent home by my boss after 4 hours because I’m still so sick and I work in a hospital.

I’m just so sick of being sick! Nasal congestion, chest congestion, a nasty cough, plus pregnancy hot flashes. The doctor told me all I can take is Robitussin DM and it’s not helping at all. I’m staying hydrated and resting but I’m not getting better 😓

Any advice?
