Salam sayang! Okay, I need you to go see your doctor ASAP or call them today, don't wait for another appointment. This is something kena check properly by your OB, boleh? I know macam scary, but honestly dating kan sometimes off by a few days, and only your doctor boleh assess properly what's happening and monitor you closely. Some of my mum friends went through different scenarios at scan time, tapi each case lain-lain, so please don't stress sendiri, let the doctor guide you, okay? Hang in there, mama. You're doing the right thing by asking.
