How to deal with a cold while pregnant?

I’m 9 weeks pregnant. I woke up with a really bad sore throat and a congested nose. I went to the doctors to rule out strep or any serious virus. I was told it’s most likely a cold. I can’t really take anything. I’ve been on the couch all day having tea and soups. I tried breathing in hot steam to open my nostrils but nothing’s working. I’ve even tried rubbing Vick’s. My nose is still clogged and my throat still hurts. Can anyone give any suggestions ? Thank you
