Uy, mama, please check with your OB agad, headaches during pregnancy need proper evaluation, lalo na kung severe or with other symptoms like vision changes. Hindi kami dapat mag-assume na normal lang yan. A few of us mums na pregnant din, nag-experience ng headaches, pero kailangan talaga ng doctor's clearance first para ma-rule out any concerns. Rest is good, pero go see your doctor para ma-ease your mind. Praying for you and baby!
