Oo mama, totally normal yan lalo na sa ganitong stage ng pregnancy! A few of us moms felt the same thing, parang pulling or slight cramping sensation kapag umaatching, especially pag mabilis ka kumilos or pag sobrang busy ang araw mo. Since it's not painful and just that slight sensation, it's likely just your ligaments stretching as baby grows, but if it gets worse or mas masakit na talaga, definitely chat with your OB just to be sure and get peace of mind, okay?
