Mama, signs of labor can vary and it's really important to call your OB or go to your nearest hospital right away to check what's happening, better safe than sorry, lalo na kayo're so close to your due date na!
I know it's scary as a first-time mom, pero ang doctors lang talaga ang makakasabi kung normal lang or if you need to go in. Wag mag-antay, contact them now, okay?
