Hindi necessarily, mama! At 37 weeks, Braxton Hicks (those practice contractions) are super common na at talagang mahaba pa ang pwedeng mangyari before labor, pwedeng dalawa pang linggo o more. A few of us moms nag-experience na ng matinding tightening for weeks bago talaga mag-go into actual labor, so it's not always a sure sign na malapit na. Best mag-check with your OB to make sure everything is normal lang and para ma-clarify kung ano talaga ang nararamdaman mo, they can tell the difference between Braxton Hicks at early labor signs based on how frequent and painful ang contractions.
