My report just says intrauterine single gestational sac noted.myometerial echodensity is homogenous.intrauterine early pregnancy.
What does it actually mean.they have called me for rescan after 2 weeks

It's saying that they see one embryo. Your doctor probably wants you to come back in 2 weeks to check to see how the pregnancy is progressing given your other post: https://www.askmehelpdesk.com/pregnancy-new-motherhood/inlaws-against-pregnancy-fear-defect-382611.html

Did you ask your doctor why they want you to come back?
