Failed intrauterine pregnancy was defined as (1) an embryonic pole 5 to 14 mm with no embryonic cardiac activity, (2) an irregular intrauterine gestational sac with a mean sac diameter of ≥16 mm and no embryonic pole, (3) abnormal growth on ultrasound image over a minimum of 7 days, or (4) yolk sac present with an …

In pregnancies with one placenta and two amniotic sacs, you will definitely have identical twins. Additionally, when your babies share a placenta, there is a greater risk for complications, such as twin-to-twin transfusion syndrome.

Intrauterine pregnancy is usually diagnosed by a positive pregnancy test and demonstration of a gestational sac in the uterus. The earliest an intrauterine gestational sac can be seen by a transvaginal scan is 4-5 weeks’ gestation (2-3 weeks embryo).

When the doctor or specialist nurse scanned you today, they diagnosed you with early intrauterine pregnancy. You may or may not have expected your pregnancy to be at an early stage. This diagnosis means that there is a pregnancy sac in the womb, but it is too small to see the baby or its heartbeat.

Intrauterine fetal demise is never the desired outcome of pregnancy, but it can happen for a variety of reasons such as a genetic disease or infection.

A heterotopic pregnancy is a rare complication of pregnancy in which both extra-uterine (ectopic pregnancy) and intrauterine pregnancy occur simultaneously. It may also be referred to as a combined ectopic pregnancy, multiple‑sited pregnancy, or coincident pregnancy.

The most common cause of IUGR is a problem before birth in the placenta (the tissue that carries oxygen, food, and blood to the baby). Birth defects and genetic disorders can also cause IUGR. A baby also may develop IUGR if the mother: Has an infection.

How accurate is the ultrasound examination? The earlier the ultrasound is done, the more accurate it is at estimating the baby’s due date. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

Ultrasound. Although the factors above may be signs of a twin pregnancy, the only sure way to know you’re pregnant with more than one baby is through an ultrasound. Some doctors schedule an early ultrasound, around 6 to 10 weeks, to confirm the pregnancy or check for issues.
