Alhamdulillah rahim okay! Placenta previa (uri bawah) memang common dalam early pregnancy, tapi kena monitor closely sebab kadang naik sendiri by third trimester, a few of my mum friends had the same thing and theirs moved up, so there's still hope lah. Best thing is follow your doctor's advice exactly (maybe more frequent scans, rest, avoid heavy lifting), jangan stress sangat sebab stress jugak boleh buat things worse, I know it's scary being first time mom, tapi at 25 weeks ada lagi masa untuk situation berubah, so stay positive but do what your gynae says
