The number of tissue layers that develop in the embryo is typically three. These three primary germ layers are the ectoderm, mesoderm, and endoderm. Each layer gives rise to specific tissues and structures in the developing organism.
If it's a human embryo, about nine months. If you're a mouse embryo, about twenty days. Gestation time in mammals varies species to species, but it's generally safe to say the bigger the animal, the longer the gestation.
Triplets occur when three separate eggs are fertilized by three separate sperm cells. Each fertilized egg develops into its own distinct embryo, resulting in three babies developing simultaneously in the womb. Triplets can be fraternal (developed from three separate eggs) or identical (developed from one fertilized egg that splits into three embryos).
After three months of consistent exercise and healthy eating habits, one can expect their stomach size to decrease due to reduced fat and increased muscle tone. This may result in a flatter and more toned appearance.
The three tiny cells produced in oogenesis are called polar bodies. They do not develop into viable eggs and typically degenerate. Their main purpose is to assist in the distribution of cytoplasm to the developing egg cell.

The first trimester ends at week 13, when the developing embryo becomes a fetus.
Food, water and vitamins.

miscarriage, stillbirth, or damage to the fetus during the first trimester (three months) of pregnancy.
during the first three months of pregnancy
The first three months, which is the time of organ generation, is the riskiest time.
At 14 weeks the fetus is about 8cm long and weighs about 40g.
All the organs of the fetus develope in first three months of missed period.
All organs of the Fetus are formed during first three months of Pregnancy. So drugs taken during this period have high chances of 'Structural' damage to the Fetus. Afterward 'Functional' damage can occur.So your Doctor will be very careful about drugs given in First Trimester ofPregnancy.
