Ay, I've heard of this from a few of my mum friends, and honestly it's usually nothing to panic about, could be normal discharge or sometimes just crystals from concentrated urine lalo na if you're not drinking enough water throughout the day. But since kina-worry mo and it's a health thing, best talaga to mention it sa OB mo on your next visit or even call lang to ask, para ma-ease your mind agad and make sure everything's okay! Drink more water muna habang naghihintay, and if may other symptoms like pain or unusual smell, that's when you really should get checked right away.
