Hindi pa po yan sure signs of labor, mama, discharge changes at body aches are common sa 38 weeks kaya mahirap mag-predict, but the combination ng pain when walking plus discharge does warrant a quick check-in with your OB para ma-rule out kung may infection or if you're already in early labor, kasi these things they can assess properly. Hopefully mabilis lang at good news, pero better safe than sorry pag may doubts, especially pag close na tayo sa end ng pregnancy! Fingers crossed na smooth ang delivery mo and walang complications.
