Ay, mama, I can hear how worried you are! Pero sobrang importante talaga na you call your OB or go to the hospital na para ma-check mo, backpain lang kasi pwedeng maraming reasons, and we can't tell from home kung ito na yung labor or something else na kailangan ng doctor's attention. A few of us moms had similar worries, and honestly, the peace of mind from getting checked is really worth it, hindi ka mag-iisa don, and they'll know exactly what's happening with you. Huwag nang mag-antay, mama, better to be safe, lalo na ganitong importante ang moment na ito.
