Mama, please see your doctor or go to your health center as soon as you can, everyday fever and headaches during pregnancy need to be checked, okay? Hindi ito something to wait out. Better safe than sorry, lalo na ngayon na pregnant ka pa lang at delicate ang stage. A few of my mum friends experienced fevers during pregnancy din, and nalaman nila may underlying cause, some needed treatment right away para sa baby's safety. Go now and let the OB check you properly!
