Uy, mama, if you're having doubts about whether it's labor na, please go to the hospital or birthing center right now para ma-check properly, hindi worth it mag-antay na lang, lalo na may sakit na ganyan! I'd really hate to guess kasi iba-iba talaga ang signs sa bawat mama, and your OB lang ang makakasiguro kung ready na to deliver or what's really happening. Better safe than sorry talaga, no? Let us know how you are after, okay? Sending you strength, mama!
