Fever And Headache

Hi mummies, I am at 29 weeks. I've been having slight fever and very bad headache the past few days with slight cough. It's on and off fever. Usually in the day will have for few hours then after will be okay but at night it will come back just before bedtime. I've been to GP and only able to prescribe me paracetamol. It's not really effective. I feel like my fever, headache and cough is getting worst despite consuming paracetamol. May I know if there is anything else I can do to help myself?
