Hai sayang, I know it's scary! Placenta previa memang kena monitor closely, your doctor is doing the right thing. A few of us mums went through this, and honestly, the best thing is just follow your doc's instructions (mostly rest, avoid heavy lifting, no intercourse) and go for that 2-week scan. Some cases do resolve on their own by third trimester, but some don't, either way, your team knows what's best for you and baby. Jangan worry too much lah, modern medicine can manage this. Just take care of yourself, rest when you can, dan tunggu next scan. Rooting for you!
