So Sick with Sore Throat & Pregnant! Help. Ughhhh

8 weeks pregnant. 1st baby. Severe throat & sinus infection. Currently using salt water to gargle, saline solution for sinus & paracetamol for pain - but I feel like death warmed up. Mom is kindly bringing me vitamin c tabs & oranges after work as husband is away on business. I cannot take antibiotics as I am incredibly allergic - long story. Please, please, please give me your advice & tips & tricks - I'm so desperate to feel better! Have our first scan on Thursday & I dont know if I'm going to make it - I feel so sore and so sick! 😰 Wish I could take a Stilpane or something!! Please Help. 🙏 ps. Pointless going to doctor - I need tried & tested advice from my Glow ladies!!!! X x
