Hey mama, normal lang yan sa early pregnancy kasi lumalaki na ang uterus mo at nag-aadjust ang body mo, pero since it's happening consistently at affecting your sleep, best talaga to check with your OB just to be sure walang ibang cause like round ligament pain or something else, don't worry, usually fine lang yan pero mas peace of mind ka after. A few of us moms experienced similar at the doctor assured us it's part ng process, pero important pa rin makita siya para ma-rule out kung may iba.
