Uy, this is something you really need to ask her OB-GYN about right away, hindi dapat self-diagnose lalo na may concern sa cervix, okay?
Pero handa lang ako makinig kung ano ang actual concern ninyo. Is she having pain, bleeding, or unusual discharge? If yes, go to the hospital na agad. Her doctor needs to check what's happening before any cleaning or treatment, kasi buntis siya at sensitive ang situation.
Tawagan agad ang OB niya or pumunta sa nearest health center, mas safe yan kaysa mag-worry lang. Rooting for her!
