Good thing you're seeing your OB tomorrow kasi that's the best way to know for sure, pink discharge at 38 weeks can be normal (especially with all those Braxton Hicks!), pero kailangan talaga i-check kung ano exactly ang nangyayari, whether it's just the mucus plug starting or something else na kailangan i-monitor, lalo na ngayon na fully effaced na ang baby. You're doing everything right by staying on top of it and not stressing too much, your body knows what it's doing, at kahit walang obvious signs of labor, you're so close na! Keep your OB updated with everything, and trust that they'll guide you on the induction situation based sa overall picture bukas. You've got this, mama!
