Hi mama! At 39 weeks, some discharge changes are normal, pero yung brown tinge na kasama nito ay kailangan i-check agad with your OB, pwede itong bloody show na sign na labor is coming, or pwede ring something na kailangan attention. A few of us moms noticed similar stuff near our due date at the doc said iba-iba, some were just normal, pero iba really needed monitoring. Better safe than sorry, lalo na at malapit ka na sa delivery, message or call your doctor right away para masure tayo na okay ka and baby!
