What does a pregnant womans body look like inside
Women undergo many physical changes during pregnancy due to hormonal fluctuations and the need to accommodate a growing fetus. Most pregnant women do not have any specific signs or symptoms after implantation, although it is not uncommon to experience minimal bleeding. After implantation, the uterine endometrium is called the decidua. The umbilical cord connects the embryo or fetus to the placenta.SEE VIDEO BY TOPIC: PREGNANT WOMAN ANATOMY - What’s Going On In There

How your body changes in pregnancy (Video)
Before pregnancy, most of the space in your abdomen is taken up by the large and small intestines. There is no real separation between the areas of your pelvis and abdomen. In the picture here, you can see that the vagina is behind the bladder sac that collects urine and urethra tube for moving urine out of bladder and body.
In its normal position, your uterus is above and behind the bladder, with the cervix protruding into the vagina. The pelvic colon, rectum and anal canal are behind the vagina and uterus. Previous Next.
When you are between 6 and 7 weeks pregnant, you may be experiencing the early signs of pregnancy: your period has stopped and you may have nausea, breast tenderness and swelling, frequent urination and fatigue. At this point, your uterus has begun to grow and become more egg-shaped.
The pressure of the growing uterus on the bladder causes frequent urge to urinate. In this image, you can see the beginnings of the placenta in the uterus. The internal organs are forming and the heart has been beating since the end of the 4th week. The embryo is floating in the amniotic sac.
Buds for the arms and legs emerge in the 5th week and, by the 7th week, buds for fingers and toes also appear. The umbilical cord is lengthening and will continue to grow, allowing the fetus freedom to move.
The 7th week represents a milestone in development: the embryo is now considered a fetus. At the 12th week of pregnancy, the placenta is much larger. It now produces the hormones needed to sustain the pregnancy. Your uterus is the size of a grapefruit and completely fills the pelvis. It rises up into the area of the abdomen, as shown in the image. The fundus, the upper end of the uterus, is just above the top of the symphysis where the pubic bones join together.
This upward growth of the uterus takes pressure off the bladder and decreases the need for frequent urination. The mucus plug, a barrier to protect the growing fetus, fills your cervical canal. The fetus is now about 3 inches long and weighs about 1 ounce. By this week, the fetus has fingernails and toenails and can open and close the fingers. The fetus will start to move, but you will not feel it yet.
By the 20th week of pregnancy, your uterus can be felt at the level of your belly button umbilicus. The pelvic colon and small intestines are crowded upward and backward. The ascending and descending colon maintain their usual positions. At this point, your uterus is especially enlarged where the placenta attaches to it usually on the front or back wall. This gives the uterus an uneven bulge. The wall of the uterus, which lengthens and thickens early in pregnancy, stretches as the fetus grows, and becomes thinner now — just 3 to 5 millimeters thick.
Your bladder moves up but not as much as your uterus, which straightens as it moves up. As your uterus moves up, it rests against the lower portion of the front of your abdominal wall, causing it to bulge forward noticeably by your 20th week.
The size of the bulge depends on how strong your abdominal muscles are. If they are firm, the uterus may be pressed against the spinal column, and there will be no noticeable bulge; if they are weak, the pressure of the uterus against the inside wall makes a sizeable bulge. At this point, you should be able to feel light movements of the fetus. The fetus sleeps and wakes at regular intervals, is more active, is about 9 inches long and weighs between a half-pound and a pound.
At this point in pregnancy, the top of your uterus is about one-third of the distance between the bellybutton and the xiphoid cartilage at the lower end of your breastbone. Between the growth of your uterus and general weight gain, you may be feeling fatigued.
Some women also experience heartburn as your uterus presses against your stomach. Your breasts are also changing to get ready for breastfeeding. First colostrum and then milk are produced by the grape-like clusters of tiny sacs alveoli deep within the breast tissue.
Clusters of alveoli form lobules, which come together to form 15 to 20 lobes. Each lobe connects to a lactiferous duct for conveying milk. As the ducts extend toward the nipple and areola darker area around the nipple , they widen into the lactiferous sinuses. These sinuses or milk pools release the milk through 15 to 20 tiny nipple openings in each breast when the baby nurses. At week 28, the fetus is about 16 inches long and weighs two to three pounds. The skin is wrinkled but will become less so as more fat builds up under the skin in the next few weeks.
Its eyes are open, and eyebrows and eyelashes were formed in the fourth month. The fetus sucks its thumb and its taste buds have developed. Fetal organs and systems are quite well developed by the 28th week of pregnancy, but the final two months of gestation are important for further maturation of all body systems and organs. By the end of the 36th week of pregnancy, your enlarged uterus almost fills the space within your abdomen. The fetus is inside the membrane sac within the uterus and high within the abdomen.
The muscles of your abdomen support much of its weight. During this week, the top of the uterus is at the tip of the xiphoid cartilage at the lower end of the breastbone, which is pushed forward. The change in the position of the heart and the upward pressure of the diaphragm may make it hard to breathe at this point.
The crowding of your stomach and intestines may contribute to discomfort after eating. Your cervix is long, thick and filled with the mucous plug. By the 36th week, your vagina and urethra are elongated and all the tissues in the perineum area between vaginal and anal openings are enlarged. The swollen perineum projects outward in the last weeks of pregnancy and readily expands during labor. The brain of the fetus is growing rapidly, but bones in the skull are soft so that he or she will fit through your vagina at birth.
The lungs are still forming. You will likely feel the fetus kicking and may be aware of rhythmic movements, which could be hiccups or thumb sucking. Another possible sensation, sudden movement, may be a startle response. In repeat pregnancies, this can happen at the time of labor. The canal of the broad, enlarged cervix is still filled with the plug of mucous. If this is your first pregnancy, the small opening at the bottom of your cervix is usually not dilated, whereas if you have given birth before, it will often be open as wide as two fingers some time before labor begins.
At this point, you may be experiencing frequent urination, increased constipation, edema water retention and aching legs or vulva. Varicose veins in the vulva, rectum and legs are also possible. This is because of the position of the uterus, the pressure of the baby's head and a loss of muscle tone as the hormone relaxin loosens your tissues in preparation for birth. Other changes at this time include increased development of blood vessels and increased amount of blood.
You can see that the round ligament is long and enlarged. It is also farther forward because of the twisting of the uterus. The enlarged uterosacral ligament is shown stretched taut by the enlarged uterus. Backaches in late pregnancy may be due to the stress of the weight of your uterus on the ligaments that connect it to your spine.
Because your uterus dropped a bit, you may be able to breathe and eat more comfortably near the end of your pregnancy. At this time, the lungs of the fetus are likely fully mature and ready to begin breathing. The fetus gains about a half pound every week at the end of pregnancy, for a birth weight of roughly 7 pounds, and is growing longer for a birth length of about 18 to 21 inches. Labor starting on its own around week 40 is a sign that your body is ready to give birth and your baby is ready to be born.

A woman's body undergoes many transformations during the nine months of pregnancy. Some of these physical changes are visible, such as an expanding belly and weight gain, while others are well known, such as an enlarged uterus, morning sickness and backaches. However, a few bodily changes may be unexpected and catch some women by surprise. One change that often takes some pregnant women by surprise is an increase in breast size, Trout told Live Science. A second unanticipated change is varicose veins in the genitals, Trout said. Women may expect varicose veins in their legs during pregnancy, but veins near the vagina and vulva can also become swollen and pop out usually in the third trimester, she said. Although swollen veins in this area can be uncomfortable, they tend to go away after delivery, Trout said. Here is a head-to-toe guide of some other physical changes that a woman's body may experience while she is pregnant. She explained that women are more susceptible to infections during pregnancy because the immune system tamps down.
