Ah, yan ay Braxton Hicks contractions, normal yan sa 29 weeks! A few of us pregnant moms get them more frequently as we approach the third trimester, lalo na if you're active or dehydrated. Try drinking lots of water, resting, and changing positions, usually lumalabas ang tense feeling after a few minutes, pero if it's painful or may spotting, better check with your OB agad just to be safe!
