Ay, napaka-common yan sa 38 weeks, girl! Those on-and-off pains could be Braxton Hicks or your body getting ready, pero honestly mahirap sabihin kung totoong labor na or not without checking with your OB kaya pls go in for a quick assessment to be sure. If the pains come back regularly or you notice other signs like consistent contractions, bleeding, or water breaking, that's when you rush to the hospital na talaga!
