Momsh, I know you're excited, but please see your OB agad, yung brown discharge and lower back pain together need to be checked properly para sure, especially if it's painful Hindi natin pwedeng i-assume kung labor na yan or something else, kaya better safe than sorry! One of my mum friends thought ganyan siya, pero turned out something else pala na kailangan ng attention. Go na sa clinic or nearest hospital kung madalian, okay? Rooting for you!
