5 weeks pregnant and scan sHow is a sac yet this ok?

At 5 weeks pregnant, it is common for an ultrasound to show only a gestational sac. The embryo is still very small and may not be visible on an ultrasound at this stage. The gestational sac is the fluid-filled sac that surrounds the embryo and provides nutrients and protection. As the pregnancy progresses, the embryo will grow and develop within the gestational sac. Typically, the embryo will become visible on an ultrasound by 6-7 weeks of pregnancy. If you are concerned about the development of your pregnancy, it is always a good idea to consult with your healthcare provider.
