Hai mama! Right-sided pain during pregnancy mmg common, tapi sebab gastrik or rahim yang stretching, it's really hard to say tanpa check-up. Sesiapa pun yang ada gastrik pun memang worst during pregnancy sebab hormon dan baby pressure la. My friend yang pregnant dulu, dia kena gastrik parah, doc dia suggest frequent small meals and avoid spicy stuff, helped her quite a bit. Tapi mama, better check with your gynae or doctor just to be safe, sebab sometimes sharp pain tu boleh jadi benda lain juga. Jangan worry too much, but don't brush it off also lah. Hope you feel better soon!
