Hay, I totally get your worry mama, placenta previa is really scary to think about! From what I've heard from a few of my mum friends, some did have their placenta move up as pregnancy progressed, especially if it started low-lying lang in the earlier trimesters like yours, so there's definitely hope pa for you. That repeat ultrasound on March 5-8 will give you clearer answers, at honestly kailangan mo talaga ng doctor's guidance on this one because placenta previa totalis needs close monitoring and the outcome really depends sa kung gaano kalayo umakyat or hindi ang placenta mo by third trimester. Marami talaga na nag-CS dahil dito, but some cases do move, so fingers crossed for your scan! Wishing you all the best with your repeat ultrasound, and make sure to ask your OB directly about your chances for normal delivery based sa positioning, they'll give you the most accurate picture.
