Ay, panay tigas ng tyan plus movement is actually pretty normal especially if you're in your third trimester, most of us experience that, usually Braxton Hicks contractions lang na practice contractions ang katawan mo. But since it's persistent and you want to make sure baby's doing okay, it's best to reach out to your OB quickly, lalo na if may pain, spotting, or kung parang labor contractions na talaga, better safe than sorry, mama!
