Ay, dapat talaga i-check mo yan with your OB or doctor, sis! Yung pakiramdam ng langgam sa underwear ay pwedeng sign ng infection o high blood sugar, pero maraming possibilities pa, like yeast infection o fungal issue, lalo na ngayon ng mainit. One of my mum friends din nag-alala ng ganito and turned out UTI lang, but better safe than sorry kaya kumuha siya ng urine test para sure.
