Oo momshie, super normal yan lalo na first trimester, marami sa amin naka-experience ng ganyan, usually dahil sa hormonal changes at dehydration pa lang talaga. Try drinking more water, rest in a dark quiet room, at kung okay lang sayo magpa-paracetamol (safe daw during pregnancy but check mo with your OB to be sure), pero syempre best approach is mag-consult ka na rin with your doctor para ma-rule out ang iba at ma-ensure na it's really just normal pregnancy headaches.
