Aah low-lying placenta, kan? A few of us experienced this juga, memang boleh bikin nervous! Tapi honestly at 16 weeks banyak placenta still naik sendiri as the uterus grows, so don't worry too much dulu, usually follow-up scan around 28-32 weeks baru confirm final position. Definitely discuss with your doctor about monitoring schedule and any activity restrictions for now, sebab setiap case beda-beda depending on exactly how low it is.
