Hindi ka nag-iisa sa ganito, sis! Baby measurements can vary kaya don't stress too much, ang importante talaga ay ang weight ay normal na para sa gestational age niya, which is a really good sign. Since bukas mo na makikita ang OB mo, perfect timing to discuss this with them directly kasi they know your full history and makakapag-explain ng maayos kung bakit ganyan ang measurements; usually it's just individual variation lang at walang problema. In the meantime, stay calm and trust the process, you're almost there na!
