Uy mama, ito talaga ay kailangan mong i-check ng doctor agad, ha, hindi ito dapat patagalin lalo na at 20 months preggy ka na. Kahit konti lang ang concern, mas peace of mind mo kung makita sya ng healthcare provider, especially during pregnancy kasi sensitive ang period na yan. Hindi ko kayang mag-advise on this one kasi medical talaga, pero please don't worry, marami akong kaibigan na nag-alala din with pregnancy concerns at lahat naging okay, but consultation is a must. Bumisita ka sa OB mo or kung urgent, pumunta ka na ng clinic/hospital. You're doing great by asking, yun ang right move!
