Mucus plug na po kaya ito?

Ay, congrats on baby number 3! It could be mucus plug na talaga, lalo na kung may slight yellowish or stringy appearance siya, a few of us went through that before labor or even weeks pa lang before, hindi automatic na sign na mag-deliver ka na agad. Since you're at 36-37 weeks and ito's your third CS, I'd really suggest you ring your OB agad just to confirm kung okay lang or if kailangan mo na mag-admit, especially since nangyari twice na kaninang umaga, better safe than sorry talaga, especially since planned CS usually, so your doc needs to know kung may changes na.
