Ay, first time mommy anxiety, alam ko yan! Honestly, labor can range from a few hours to more than 24 hours depending sa dami ng factors, baby's position, if it's your first time, kung medicated or natural birth ka, kaya talaga walang standard na "how long." Marami sa amin nag-labor ng 12-18 hours sa first baby, pero may kaibigan akong almost 30 hours na bago mag-push, tapos mabilis lang pala ang actual delivery part, so hindi mo alam talaga until you're in it. Best advice is mag-talk to your OB about what to expect based sa your situation, pero be prepared na it could be longer than you think, important na may good support system ka and rest when you can during labor. Breathe, mama, you'll get through it!
