Ay, ganyan talaga with low-lying placenta, ang good news is maraming cases na nag-resolve pa by 32-34 weeks, so don't lose hope yet kasi may time pa! I'd really suggest asking your OB kung ano exactly ang plan if it doesn't move, and kung kelan talaga sila gusto mag-schedule ng CS based sa your scan results, kasi iba-iba talaga depending kung gaano kalaki ang placenta previa mo, at they might want to recheck in a few weeks pa bago mag-commit sa date. Either way, 37-38 weeks ang standard for planned CS if it doesn't resolve, but mas nakakatakot pang think about emergency deliveries kaya the monitoring route you're doing is really the smart move. Fingers crossed na mag-migrate pa yan! Keep us posted, and take care of yourself, mama!
