Oo, normal yan! Yan ang Braxton Hicks contractions, parang practice contractions lang ng uterus mo para mag-prepare for labor. Sa ganyang gestation mo, mas common na talaga sila, lalo na kung busy ka or dehydrated ka. Pero if sobrang sakit, frequent ng husto (like every 5 minutes), or may bleeding or fluid discharge, better check with your OB agad para sure lang, okay?
