Ahhh I feel you, sakit kepala teruk memang mencabar especially masa pregnant! A few of my mum friends cakap rest in a quiet, dark room membantu, and drinking lots of water sebab dehydration is a common trigger during pregnancy. Jangan lupa makan on time juga, low blood sugar boleh trigger migraine. That said, sakit kepala teruk macam ni memang kena check dengan doctor especially since you're in week 22, better safe than sorry, kan, bcos sometimes it can be related to blood pressure or other pregnancy things. Panadol is safe during pregnancy but if it's happening every day, your doc should know so they can help you properly
