Oo, normal yan, mama! Yan yung Braxton Hicks contractions, practice contractions lang ng uterus mo, especially pag active ka or pagod ka. A few of us nag-chat about this din, mostly nakikita namin siya kapag nag-exercise or nag-household chores kami, then after a few minutes, balik normal na. Just make sure nag-rest ka and nag-hydrate well pag nangyari yan, pero kung persistent siya or may pain, spotting, or anything else na unusual, better check with your OB na lang to be safe, ha.
