Uy, I feel you, that uncertainty is nerve-wracking! But please stay in touch with your doctor or the birth center regularly today, especially since you're already having consistent cramps, back pain, and leg cramps na parang labor signs, they'll know best kung ready na talaga ang baby or if it's still early labor. Your body's doing its thing at 38+6, kaya stay hydrated, rest when you can, and don't hesitate to go back to the center if the pain gets stronger or closer together, or if anything feels different. You've got this, mama, lapit na talaga!
