How much rom should you have at six weeks?

At six weeks, a developing fetus typically has a crown-to-rump length of about 4 to 6 millimeters. In terms of gestational age, this corresponds to roughly six weeks since the last menstrual period, or four weeks post-conception. The amount of amniotic fluid can vary, but it generally starts to increase significantly around this time, providing a protective environment for the fetus as it grows. Regular ultrasounds can help monitor fetal development and fluid levels during this stage.
