Alangkah baiknya, jangan risau sangat dulu ye. Ramai mums I know yang dapat placenta previa at 30 weeks, tapi it can still move up, the uterus grows and stretches, so the placenta repositions itself. Ada yang gerak drastically between 30 and 34 weeks, so there's definitely hope lagi. Most cases resolve on their own by third trimester, especially if it's not complete previa. Bagaimanapun, I'd say follow up closely dengan doctor or specialist mo, do your scans as scheduled, and maybe take it easy la, jangan terlalu stress. Insyaallah boleh settle sendiri. Hang in there, mama!
