Ay, that fishy smell kahit walang itch or discharge changes is usually something to check with your OB about, mama, could be bacterial vaginosis or something else na need proper testing lang. A few of us had the same concern and turns out it was just imbalance na need antibiotics, so hindi big deal once you confirm with the doctor! Better safe than sorry talaga, especially if it's bugging you, kaya go get it checked out okay? Sending love!
