I feel you! I'm currently experiencing super bad cough till I'm having headaches and sore throat/lost sense of smell and appetite.. unable to sleep due to coughing in the middle of the night. :( I've went to see the doctor and thankfully they gave me pregnancy safe cough syrup which reduce the cough. Normal paracetamol are safe. I just try to drink as much water and get more rest. Get well soon 🙏
Would suggest for doctor visit instead of just paracetamol. Perhaps, they will prescribe you with medication that suits you at this point you are on first tri.
