Sore throat and pregnancy

Sabrina🌸 • 🤵👰7/25/15 👧🏼12/6/13 👼2/21/15 👦3/26/16 👧6/27/18 I`m 26 and have 3 beautiful babies! Due with #4 September 2020

I just found out yesterday that I am pregnant. I've had a sore throat since after christmas. At first it wasnt that bad but now I feel like knives are in my throat. I have so much saliva build up I'm scared to swallow. I dont think I've ever had a sore throat this bad ever. Practically in tears. Does anyone have any remedies that helps with the pain? But is safe for pregnancy?
