Mama, please see your doctor or go to the clinic/hospital ASAP, yan hindi dapat i-ignore lalo na 5 days na sobrang sakit. Headaches during pregnancy ay normal talaga, pero kung ganyan katagal at grabe ang pain, kailangan niyang tingnan ng professional para ma-rule out ang something serious. Don't wait pa, okay? Your health and baby's health come first. Sending you hugs, praying it's nothing serious!
