hello there.. You should not let yourself be febrile during early pregnancy as it can lead to abortion. So when you feel you have fever , just record temperature and take paracetamol as whenever you have temperature , baby s temperature is 1degree more than you which is risky for the baby., Also see a gynecologist personally so as to know the site of infection which is causing fever as unless treated you would keep having fever episodes. Paracetamol is just a symptomatic treatement. Keep adequate fluid intake and nutrition
