In human pregnancies, a baby-to-be isn't considered a fetus until the 9th week after conception, or week 11 after your last menstrual period (LMP). The embryonic period is all about the formation of important systems of the body. Think of it as your baby's basic foundation and framework.

Level 2 Ultrasounds A Level 2 ultrasound is a comprehensive, detailed evaluation of fetal anatomy and development. It is a much more in-depth evaluation of the fetus than a standard or Level 1 ultrasound. The ultrasound examination is usually performed at about 20 weeks gestational age.

The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development. An embryo is termed as the foetus in the beginning in the 11th week of pregnancy.
