Uy mama, at 39 weeks na yan, go to your OB or hospital na agad para tiyakin kung labor pain na o something else, lalo na kung grabe ang sakit at hindi mo kaya tolerate, okay? Hindi kami dapat mag-assume dito kasi kailangan ng doctor to check you properly. Once you get checked and everything's clear, a few of us mums swear na ang positioning helps, try different sleeping positions, or sit up for a bit kung nakahiga ka. But seriously, don't wait, go na, especially at gabi kung parang labor sign talaga. Better safe than sorry, 'no? Rooting for you, mama!
