Uy mama, yan ang Braxton-Hicks contractions, super normal yan sa 6 months, a few of us preggy friends namin palagi nyang naramdaman din, lalo na pag busy or dehydrated kami! The thing is, kung painful na talaga or may spotting, or kung parang regular na talagang consistent, better check with your OB lang para makapagpacalmative kayo both, kasi minsan anxiety din nag-trigger ng mas maraming tightening. Stay hydrated and rest when you feel it, pero don't worry, most of the time harmless lang yan!
