-Determine the gender of the individual. -To tell if 2 cells belong to the same species. -To detect the genetic abnormalities in Prenatal diagnosis.
I would say the safest answer to this question is the lack of prenatal care. Meaning, a myriad of conditions that are treatable such as preclampsia are often undetected and could present a signficant health risk to the mother and child during delivery.
Doctors count from the first day of your last period, LMC, as the first day of your pregnancy. In reality you typically will ovulate and become pregnant about 10-16 days after that. They also take into matter the length of your cycle, how long between periods. That's why 2 weeks early or 2 weeks late is considered normal for the prenatal period. As every woman ovulates on a different day of her cycle. A 12 week ultrasound will likely pinpoint how far along you are as most babies grow at the same rate for the first 3 months.

During prenatal development, a particular organ or body part is most vulnerable to exposure to teratogens during its:
Prenatal development begins at the moment of conception when a sperm fertilizes an egg to form a zygote. This zygote then undergoes rapid cell division and differentiation, eventually developing into a fetus.
First Stage: The first two weeks after conception are known as the Germinal stage. Second Stage: The next six weeks of development are known as the Embryonic stage. Third Stage: The remainder of prenatal development is known as the Fetal stage.
Prenatal development occurs in three main stages: the germinal stage (first two weeks after conception), the embryonic stage (weeks 3-8), and the fetal stage (weeks 9-birth). During these stages, the fertilized egg undergoes cell division, differentiation, and organ formation, leading to the development of a fetus.
The last 7 months of prenatal development typically involve rapid growth and maturation of the fetus. Organs and systems continue to develop and reach functional levels, and the fetus gains weight in preparation for birth. During this time, the fetus also practices breathing and swallowing to prepare for life outside the womb.

Factors that can affect prenatal development include the mother's health, nutrition, exposure to harmful substances (such as drugs and alcohol), genetics, and stress levels. Additionally, environmental factors like pollution and infections can also impact the development of the fetus.

The germinal period is the shortest period of prenatal development, lasting approximately two weeks. This period begins at fertilization when the egg is fertilized by sperm and ends when the fertilized egg attaches to the uterine wall.
