Hi mama! Honestly, discharge during pregnancy can be tricky kasi marami pang factors, pero yung light yellow-green at brown colors, lalo na kung may smell or itch, dapat talaga i-check mo na with your OB para sure lang, kasi sometimes it's just hormones pero sometimes it needs treatment. A few of my mum friends had similar concerns and hindi sila nagpahintay, nagpacheck agad, better safe than sorry talaga, especially pag pregnant! Let your doctor know din kung may itch, pain, or foul smell para guided siya sa check-up.
