Uy, 7 weeks ka lang, please check with your OB/doctor agad about that headache, lalo na kung grabe at hindi nawala. Hindi dapat basta-basta ang ganitong symptoms during pregnancy, okay? Once your doctor gives you clearance, a few of us moms find na rest, cold compress, at staying hydrated helps talaga. But really, go see your doctor first para sure na lahat okay with you and baby. Take care, mama!
