Hey mama, matigas na tiyan at ganyan kalayo is usually Braxton Hicks (practice contractions), which is totally normal around this stage! But kung sobrang painful, irregular, may spotting, or parang actual labor cramps, better have your OB check you out agad lang para ma-rule out anything else, better safe than sorry, di ba, especially ngayon na malapit na natin ma-meet ang baby! Kumusta ka naman overall, any other symptoms?
