Ay, kahit na common ang discharge changes towards the end of pregnancy, mas better na i-check mo agad with your OB para ma-rule out kung bloody show na or something else, pinkish discharge combined with being 37+ weeks can mean different things, at gusto mo knowing exactly what's happening. A few of us had similar experiences and ang doctors really want to know kaagad pag may color change, so don't wait, call them today lang!
