Ongoing pregnancy. Ultrasound imaging of an embryo at 14 weeks of gestation.
Normal pregnancy development and the ultrasound check of the embryo after the 12th week mark the ongoing pregnancy. Ongoing pregnancy (more than 12 weeks) is an important time point of a gestation. Modern publications in international journals use ongoing pregnancy rates as a measure of success of an IVF cycle. Statistically, out of 100 positive pregnancy tests (biochemical pregnancies), 83-85% reach ongoing pregnancy. The remaining pregnancies (15-17%) will result in a miscarriage or result in only a biochemical pregnancy (rise and fall of hCG). The same percentages are also valid for natural conception.
