Hai mama, I understand lah, plasenta previa memang scary to deal with, especially at 29 weeks. Type 3 means your placenta is covering part of the cervix, so your doctor will be monitoring you closely sampai deliver, some cases resolve on their own as the uterus grows, some don't, but either way your medical team akan guide you through it. This is really something to discuss in detail with your OB-GYN about what to expect and whether vaginal delivery is still an option or kalau kena plan for c-section, sebab every case is different. Hang in there mama, many of us go through this and manage fine, just make sure you follow up regularly with your doctor and jangan take any risks.
