After IE........

Hay, mahirap sabihin talaga, sometimes after IE (internal exam) may increased mucus discharge talaga because the cervix was touched, pero if it's the actual mucus plug, it's usually thicker, maybe with a bit of color or blood-tinged, at parang one-time thing lang, hindi flowing continuously. Since you're already 38+ weeks, better call your OB na lang to confirm, kahit parang overthinking, mas safe, lalo na at 1cm dilated ka na, so best na marinig from your doctor kung anong timeline na ang expect mo!
