Bes, go see your OB agad, chills at headache during pregnancy need checking to rule out anything na kailangan ng immediate care, kaya better safe than sorry! Your doc will examine ka properly, at depending sa findings, either ibigay ang safe options for you or mag-refer if needed. Wag mag-alala, ang OBs dito alam nila kung ano ang pregnancy-safe, so you're in good hands. Mag-hydrate ka in the meantime at rest as much as you can, okay? Let me know how the checkup goes!
