Pregnancy and childbirth What is the pregnancy sac

 Gestational sac

The uterine cyst is the first sign of pregnancy that can be detected using ultrasound images (in English: Ultrasonography), specifically when the diameter of the gestational sac is about 2-3 mm, so by the fifth week of pregnancy, a gestational sac appears. Which forms the sac surrounding the fetus before the appearance of the fetus itself in the ultrasound images, and the detection of the pregnancy sac is used to determine the age of the pregnancy, and to make sure whether the pregnancy is normal or not, for example the growth of a pregnancy sac in one of the fallopian tubes instead of inside the uterus indicates On the occurrence of an ectopic pregnancy [1] [2] [3]
