Pregnancy is a fascinating journey that leaves many of us in awe. Studies now equate the journey of pregnant women with Olympic-level athletes for the energy and endurance required. While pregnant women have to deal with so many things, from unusual cravings to morning sickness, bringing a new life into the world is a miracle in itself.
Many changes and adjustments occur in a woman’s body during this time. These changes allow the mother and the baby to endure the nine months safely. Some changes a woman’s body undergoes are significant (and uncomfortable), such as how a woman’s organs shift around to make space for the fetus. But it’s all worth it in the end when that new life arrives.
While this time is already full of excitement and anticipation, some facts about pregnancy make this journey even more magical. We’ve compiled a list of 15 magical facts for everyone to enjoy, pregnant or not.
1. It All Begins With One Cell
Life begins with a single cell smaller than a grain of salt. This tiny cell, a zygote, holds the genetic blueprint necessary to develop into a human being.
This blueprint is made of and contains the instructions for every characteristic, from eye color to personality traits. From this tiny cell, the process of growth and development starts, ultimately resulting in the creation of a new life.
2. The Heartbeat Starts Early
A milestone in the fetus’s development occurs 22 days after conception when the baby’s heart starts beating. Just to think, after this moment, that heartbeat carries them through the rest of their lives.
By week 6, the heart is pumping at about 110 beats per minute, twice as fast as an adult’s. This means a baby’s heart will have taken over 50 million beats before they are even born! This rapid beat helps to deliver oxygen and nutrients to the growing embryo.
3. Fingerprints Are Formed in the Womb
An exciting part of the baby’s development occurs at about 17 weeks of pregnancy. During this time, the unique patterns of fingerprints begin to form.
These intricate patterns of ridges and valleys are so distinct that no two individuals, even identical twins, have the same fingerprints. This remarkable trait has been used for centuries as a means of identification.
4. A Superhuman Sense of Smell
Pregnancy often comes with a heightened sense of smell. This increased sensitivity may seem superhuman at times, possibly due to hormonal changes.
It helps pregnant women detect potential dangers, such as spoiled food or harmful chemicals, and protects the developing fetus from exposure to harmful substances.
5. The Expanding Uterus
One of the most amazing changes during pregnancy is the incredible expansion of the uterus. This organ, normally about the size of a lemon, can grow 500 times its original size to accommodate a developing fetus.
This growth is made possible by combining hormonal changes and tissue growth. After childbirth, the uterus slowly contracts and returns to its pre-pregnancy size within about six to eight weeks.
6. Baby’s First Poop is Green
A newborn’s first bowel movement that occurs right after birth, known as meconium, is a dark green, tar-like substance. This unique stool is made of materials the baby has ingested while in the womb, including amniotic fluid, bile, and shed skin cells.
Meconium usually passes within the first few days of life. This is an important milestone in a newborn’s digestive system development.
7. Pregnancy Increases Blood Volume
During pregnancy, blood volume increases by 40 to 50 percent. This rise is important for providing the extra oxygen and nutrients needed for a healthy pregnancy. The additional blood nourishes the growing fetus and placenta, ensuring proper oxygen delivery and waste removal.
This change highlights the body’s impressive intuition and ability to adapt to the unique demands of pregnancy.
8. The Placenta is Nature’s Life Support System
The placenta is the fetus’s lifeline during pregnancy. It connects the mother and baby with oxygen and nutrients, along with removing waste like carbon dioxide.
This fascinating vascular organ also produces various hormones that help to regulate fetal growth and the mother’s metabolism and help prepare the body for childbirth.
9. Babies Can Taste in the Womb
Babies can actually taste in the womb. Taste buds develop around eight weeks of pregnancy, allowing the fetus to experience flavors from the mother’s diet.
These early tastes can influence food preferences later in life. Studies show that babies exposed to certain flavors in utero may be more likely to accept those foods as they grow.
10. A New Organ Grows and Disappears
The corpus luteum is a temporary gland that appears in a woman’s body after ovulation. It produces progesterone, a hormone needed to maintain the uterine lining and support early pregnancy.
It remains active until the placenta takes over progesterone production and then dissolves. This marks an important shift as the placenta becomes the main source of hormones for the growing fetus.
11. Pregnancy Affects Voice Pitch
Pregnancy can have a surprising effect on a woman’s voice. During pregnancy, the pitch of a woman’s voice may become low due to hormonal changes, particularly the rise in progesterone.
This change can last a while after childbirth, too, but the voice usually returns to its normal pitch eventually. It’s one of the many ways pregnancy affects the body.
12. Babies Cry in the Womb
Babies can cry in the womb, but the cry is silent. Ultrasounds have shown them making mimic movements, like opening and closing their mouths, extending their tongues, and swallowing.
Different studies have observed this behavior. It can begin as early as 24 weeks, which shows how amazing the process of fetal behavioral development is.
13. Mother’s Body Provides the Perfect Temperature
A pregnant woman’s body adapts to meet the needs of pregnancy, including regulating temperature. Many pregnant women have a slightly increased core body temperature for the duration of the pregnancy, which allows the developing baby to stay at the ideal warmth for growth.
This natural adjustment is one of the many ways the mother’s body supports and protects the fetus.
14. Pregnancy Can Improve Autoimmune Conditions
Pregnancy can have a positive effect on some autoimmune diseases. Women with conditions like rheumatoid arthritis often see a reduction in symptoms or even a temporary remission during pregnancy.
This change likely results from immune system adjustments that help protect the developing fetus. Researchers are still studying the exact mechanisms, but pregnancy can significantly influence the immune system and provide relief for women with autoimmune conditions.
15. The Mother’s Emotions Affect the Fetus
A mother’s emotions can greatly impact her fetus’s development. Research shows that stress hormones released by the mother can cross the placenta and affect the baby’s stress response.
Chronic stress may lead to premature birth, low birth weight, and emotional challenges for the child. Pregnant women need to manage stress using relaxation techniques, mindfulness practices, and support from loved ones. Positive emotions, like joy, gratitude, and love, can promote a nurturing environment for the developing fetus.
