Tahniah dulu on your pregnancy! Sakit perut dan sakit kepala memang boleh jadi normal dalam early pregnancy sebab hormonal changes and all, tapi since you're experiencing it frequently, better to check dengan your doctor atau clinic untuk sure, they'll give you peace of mind and make sure everything's okay with baby. A few of the mum friends around me also had similar complaints early on, tapi once doc confirmed everything was fine, they felt so much better lah.
