Sis, please see your doctor or go to the nearest clinic para sure, better safe than sorry lalo na ngayon na buntis ka na! Headaches during pregnancy can be normal para sa iba, pero kailangan i-check ng doctor mo especially kung bagong symptoms pa lang or if it's getting worse. A few of us mamas nag-experience din, pero lagi kaming sinabi ng OB namin na importante i-report agad para ma-rule out kung may ibang dahilan. Take care of yourself, ha!
