Oo naman, normal yan sa pregnancy, ang Braxton Hicks contractions na yan, parang practice lang ng katawan mo bago ang actual labor, kaya don't worry! A few of my mum friends said ganyan din sila around that time, pero lalo pang naging frequent as they progressed, so basta hindi painful and walang bleeding, you should be okay lang. Though kung worried ka talaga or kung may pain na kasama, better check with your OB na lang para peace of mind mo, okay?
