Ay sis, a month without period plus white discharge na malakas ang acid, kailangan mo talaga magpa-check sa doctor as soon as you can, okay? Could be marami pang reasons, pero hindi dapat i-guess lang yan dahil the timing and symptoms matter. One of my mum friends had similar and turned out she was pregnant, pero may iba rin na hormonal imbalance lang, so really better na marinig mo ang professional. Don't worry too much in the meantime, pero please don't delay the check-up, pregnancy test din seryoso whether you're trying or hindi. Let me know after kung ano na-figure out nyo!
