Sick during 2nd trimester - what to take?

I caught the flu, cough and sore throat recently and am 14 weeks pregnant. I think a fever is coming too although the last I measured it was 37.3 degrees so not considered fever yet. I have a normal temperature of 36+ normally so this is higher than normal for me. GP gave me chlorpheniramine (anti histamine) which I guess is for the flu. I’m allergic to painkillers like panadol / paracetamol so I can’t take them. Wonder if I should see another GP.. I called by gynae but only got advice from the receptionist who told me to take off the counter medicine but I read online that they are not safe for pregnancy so I’m confused. What should I do? Am worried the illness will affect the baby. Appreciate some advice! #firsttimemom #advicepls
