Aw, mama, ang sikmura pain sa pregnancy ay super common lalo na around mid-pregnancy like you, kaya don't worry! A few of us preggy moms experience this din, sometimes it's ligament stretching, gas, or kahit constipation lang na frequent sa buntis, pero para sure na okay lang ang baby mo and walang serious, better check with your OB para ma-rule out anything else at ma-advise properly. In the meantime, try small frequent meals, drink lots of water, and rest as much as you can, siguro makakatulong din yan. Wishing you a smooth pregnancy, mama!
