Pregnancy is a period of significant physical and emotional changes in a woman's life. Over approximately 40 weeks, the body prepares to give life to a new human being. During this process, different stages are distinguished that mark the development of the fetus and the changes in the mother's body. Understanding these stages is essential to accompany the pregnant woman on this journey of transformation.
Stage 1: Conception
Conception marks the beginning of pregnancy and occurs when the egg is fertilized by a sperm. This stage usually occurs around the second week of a woman's menstrual cycle. During conception, the zygote is formed, which is the first embryonic cell.
Characteristics of the conception stage:
- Formation of the zygote.
- Migration of the zygote towards the uterus.
- Beginning of cell division.
Stage 2: Embryonic period
This stage covers from the third week to the eighth week of gestation. During this period, the embryo undergoes rapid growth and differentiation of tissues and organs. It is a crucial moment in the development of the future baby.
Characteristics of the embryonic period:
- Formation of basic structures such as the nervous system, heart and lungs.
- Appearance of the first limb sprouts.
- Development of fundamental tissues such as skin and brain.
Stage 3: Early fetal period
From the ninth week to the twelfth week, the embryo becomes a fetus. During this stage, organs and systems continue to develop and become more complex. Physical characteristics of the future baby begin to be distinguished.
Characteristics of the early fetal period:
- Consolidation of organs such as the liver, kidneys and lungs.
- Appearance of nails on the fingers and toes.
- Development of the external genitalia.
Stage 4: Mid-fetal period
From the thirteenth week to the twenty-sixth week, the fetus continues to grow and mature. During this stage, there is a rapid increase in weight and height, and the baby becomes increasingly active in the mother's womb.
Characteristics of the mid-fetal period:
- Fetal movements perceptible to the mother.
- Development of the digestive and respiratory system.
- Formation of subcutaneous fat.
Stage 5: Period late fetal
From the twenty-seventh week until birth, the fetus prepares to go out into the outside world. During this final stage of pregnancy, the baby quickly gains weight and positions itself for birth.
Characteristics of the late fetal period:
- Complete development of organs and systems.
- Considerable increase in weight and height.
- Head positioning for childbirth.
Stage 6: Labor and birth
Birth marks the end of pregnancy and the beginning of the baby's life outside the mother's womb. During this process, the woman experiences uterine contractions and dilation of the cervix that allow the fetus to emerge. Birth is a unique and exciting event that ushers in a new stage in the life of the family.
Characteristics of labor and birth:
- Onset of uterine contractions
- Progressive dilation of the cervix.
- Expulsion of the baby and placenta.
In summary, pregnancy is made up of six different stages, each with unique characteristics and processes. From conception to birth, the development of the fetus and the changes in the mother's body are amazing and wonderful. It is essential to accompany the pregnant woman during this journey, providing emotional support and special care to ensure a healthy pregnancy and safe delivery.
