Ah sis, normal lang yan sa 30 weeks, marami sa amin na nag-experience ng ganitong cramps, parang talagang may dadating na regla pa lang, pero Braxton Hicks contractions yan usually! Pero since ongoing siya, mas better talaga mag-check ka with your OB para ma-rule out kung may iba pang concerns, lalo na if may bleeding or heavy spotting, okay?
