Anak, given na 37 weeks and 3 days ka na, it's really important na makita mo agad ang OB mo or go to the hospital para ma-check properly, belly pain with that kind of discomfort at ganitong stage kailangan i-evaluate ng doctor kaagad, hindi dapat i-guess. A few of us moms in my circle went through different things near the end ng pregnancy, pero honestly, para sa peace of mind mo at ng baby, better safe than sorry talaga. Message your OB right now or head to the nearest hospital, ha? Take care of yourself!
