Transvaginal ultrasonography showing a gestational sac with a diameter of 28 mm, corresponding to a gestational age of approximately 7 weeks and 5 days. It contains a yolk sac (protruding from its lower part) but no embryo, even after scanning across all planes of the gestational sac, thus being diagnostic of an anembryonic gestation.
At early presentation of pregnancy at around 6 weeks, early dating ultrasound scan may be offered to help confirm the gestational age of the embryo and check for a single or twin pregnancy, but such a scan is unable to detect common abnormalities. Details of prenatal screening and testing options may be provided.
Monoamniotic twins are identical or semi-identical twins that share the same amniotic sac within their mother's uterus.

[1] [2] They share the placenta, but have two separate umbilical cords.
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]

Miscarriage rates among all fertilized zygotes are around 30% to 50%. [1] [7] [60] [123] A 2012 review found the risk of miscarriage between 5 and 20 weeks from 11% to 22%.
