This ultrasound is performed from the 6 weeks to 11 weeks of gestation and shows the Actual Week of pregnancy as well as growth status of the fetus.
By ultrasonography performed during those weeks, it is possible to confirm the number of fetus (whether pregnancy is singleton pregnancy or multiple pregnancy) and intrauterine pregnancy.
It will be helpful for pregnant women who is not sure about their gestational week (pregnant women who don’t know, or aren’t sure about, their last menstrual date), pregnant women who have suffered from miscarriage or had ectopic pregnancy, and pregnant women with pelvic pain or bleeding.
