At 10 weeks pregnant, your baby measures between 31 mm (1.22 inches) to 42 mm (1.65 inches) from crown to rump – about the length of a key lime. In the next few weeks, your baby's length will grow exponentially.
This week is an exciting milestone in your baby's development. At the end of pregnancy week 10, your baby will no longer be considered an embryo. He or she is now a fetus. Your baby will undergo the most rapid growth in the fetal period, and he or she is now at lower risk for congenital malformations (physical birth defects).
Fact: A majority of congenital malformations occur during the first 9 weeks of gestation.
At 10 weeks pregnant, all of your baby's vital organs (such as the brain, liver, kidneys, and intestines) have formed and they're beginning to function. These internal organs will further develop as your pregnancy week by week continues.
For the first time in fetal development, your baby's fingers and toes are separated (no longer webbed). Nails are beginning to form on your little one's digits. At 10 weeks pregnant, your baby has the ability to bend his or her arms and legs.
Your baby's skin is very translucent at 10 weeks pregnant, but "peach fuzz" is starting to cover your baby's skin. An outline of your future child's spine can be seen through the skin, and spinal nerves are now visible.
At 10 weeks pregnant, the yolk sac is shrinking away. It is no longer needed to provide your baby's nutrition, since the placenta is now mature and fully functioning.
Your baby can swallow at pregnancy week 10, so he or she is spending a lot of time swallowing amniotic fluid. Consider it a practice run for breathing after birth. Amniotic fluid also helps he respiratory and digestive systems develop.
At 10 weeks pregnant, you may desperately want to look pregnant, but you won't be showing for a few extra weeks. (Most women won't start sporting a "bump" until their second trimester, though second-time mothers may begin showing sooner.)
Pay attention to your abdomen. In the next few weeks, your partner may start to comment on the changes in your profile. Your belly may even be slightly more rounded at 10 weeks pregnant.
Even though you don't look too pregnant, you are probably feeling quite pregnant. Morning sickness, fatigue, and other common pregnancy symptoms can make you really hate the first trimester. Fortunately, you only have three weeks left to go until you reach that wonderful honeymoon of pregnancy - the second trimester!
At 10 weeks pregnant, you have three weeks left in the first trimester. Hang in there – it won't be long before all your uncomfortable symptoms disappear, or become less severe.
Morning sickness might be at its worst at 10 weeks pregnant. Feeling nauseous and queasy can be a challenge to deal with, but it won't last forever. Up to 50 percent of pregnant women with nausea or vomiting in the first trimester get complete relief from their symptoms by 14 weeks pregnant (the second trimester). Only a handful of women feel nauseous until they deliver.
Gassiness is also common at 10 weeks pregnant. If you're finding that you're passing gas or burping at the most inconvenient times, you aren't alone. You can blame your pregnancy hormones for your gassiness. To prevent gas, it's a good idea to avoid foods that produce a lot of gas – certain as fried and fattening foods. Eating smaller meals during the day, which helps your stomach digest food better, can also help you cope with this annoying pregnancy symptom.
Occasional bouts of dizziness may also occur at 10 weeks pregnant. Although it can be worrisome, feeling dizzy or lightheaded occasionally is a normal pregnancy symptom and it's due to the changes in your cardiovascular and nervous system when you're expecting. When you start to feel dizzy, lie down on your left side (which enhances blood flow to your heart) and you should feel better soon. Remember to take things slow and don't make too many sudden movements. Sometimes, standing up too fast can cause blood to pool in your legs and this can also contribute to dizziness in pregnancy.
Acne and breakouts are also normal at 10 weeks pregnant. The higher levels of pregnancy hormones in your body can cause your skin to produce extra oil – leading to pimples, breakouts, and acne. You may feel like you're a teenager again. Not to worry – acne might go away later in pregnancy, and your skin should return to normal after your little bundle of joy is born.
Vision changes are another pregnancy symptom that some women experience at 10 weeks pregnant. You have double the blood volume in pregnancy, and this increased circulation can thicken and curve the corneas, and it can make your vision blurrier. Your eyes may also feel drier now that you're pregnant. Your vision should go back to normal after delivery.
Now that you’re only three weeks away from the end of your first trimester, you will start to gain some weight. Your weight gain at 10 weeks pregnant is roughly one to three pounds. By the time you reach the end of your first trimester, you may gain an additional two or three pounds.
By 14 weeks pregnant (the beginning of the second trimester), some pregnant women have gained five or six pounds in total. You’ll want to aim for the recommended weight gain for your body size. Average sized women should only gain between 25 and 35 pounds during their pregnancy.
Both excessive pregnancy weight gain and inadequate weight gain is associated with adverse infant outcomes. The Institute of Medicine (IOM) has set guidelines for weight gain in pregnancy. Pregnancy weight gain above the recommended IOM guidelines is more common that pregnancy weight gain below the guidelines. Unfortunately, women who gain more than the recommended pregnancy weight give birth to babies with more problems than the babies born to women who gained weight within the recommended guidelines.
It is also known that inadequate weight gain during pregnancy clearly places your baby at an increased risk for problems at birth. Weight gain in pregnancy both over and under the recommended Institute of Medicine guidelines will increase the chances of your baby having problems at delivery and after birth. The more controlled your pregnancy weight gain is the healthier your baby will be.
At pregnancy 10 weeks, you may not feeling up to cleaning, but once you start to feel better and get more energy, you may want to do some spring cleaning before your belly gets too big. Cleaning during pregnancy is generally safe, but you’ll need to take some safety precautions.
When cleaning, you’ll want to wear long sleeves, rubber gloves, and long pants. You don’t want any chance of chemicals touching your skin. When you’re expecting, any ingredient can cross the placenta to your unborn baby. So you’ll want to minimize this risk in any way possible. Another way to stay safe when cleaning is to use natural, nontoxic products. For example, lime juice and vinegar are effective cleaners. You can also find many environmentally friendly cleaners on the market.
If you start to get dizzy or feel nauseous at any point in your cleaning session, you should walk away and go outside for some fresh air.
It is important to know that any exposure to toxins at 10 weeks pregnant (and throughout your pregnancy week by week) can be damaging or harmful to your little one. Your baby's health and well-being depend in large part upon your ability to take care and to protect him or her during your pregnancy.
A common exposure that some women may not consider during pregnancy is second hand smoke. Second hand smoke can be harmful particularly during pregnancy. If you find yourself in an environment where people are smoking, remove yourself as quickly as possible. Don't hesitate to address your needs or assert yourself during this important time. Most people will certainly understand your concerns and will be more than happy to accommodate any requests to avoid exposing your baby to unnecessary toxins.
Many women are concerned with genetic testing during pregnancy. There are some tests that are common to most women during pregnancy, while others are performed only under special circumstances. Women who are of advanced maternal age, over 35 years of age, may opt to undergo a test referred to as chorionic villus sampling or CVS, which can help detect genetic abnormalities that might lead to Down syndrome and other disorders.
Chorionic villus sampling is a test is typically conducted between the 9th and 11th weeks of pregnancy. There is a small risk of miscarriage associated with the procedure (about 1 percent), thus you should discuss the risks with your healthcare practitioner prior to deciding to undergo this test. CVS is considered one of the more invasive tests that can be performed during pregnancy, and it is usually only performed in high risk pregnancies, such as a woman with a family history of genetic hereditary disease or one who is older than 35 years of age.
The triple screen test is a common and safe test performed during pregnancy. It is a non-invasive blood test taken between the beginning of the 15th week and the 17th week. This test measures levels of three proteins in the blood, AFP, HCG and UE3. The levels of these proteins are compared with the mother's age and ethnicity of the parents and can determine the probability of a potential genetic problem in the baby. Some of the more common problems the test can help identify include:
Downs syndrome
Neural tube defects (defect of the lower spine)
Babies at risk for low birth weight and premature delivery
Ventral wall abnormalities (defects of the umbilical cord and bowel)
It is important that you remember that no genetic test is 100% accurate. The triple test is a screening instrument and not a diagnosis. That means that while the test may indicate your fetus is at risk for Downs Syndrome, it doesn't mean that your baby will be born with this or any other disorder. In fact, many women can receive false positive tests. A false positive test is usually a result from your calculated due date being incorrect.
If your test results from a triple screen come back positive, your physician may recommend an amniocentesis, which is another invasive procedure that examines fluid from the amniotic sac. Amniocentesis requires that a needle be inserted through your abdomen and into the uterus. Your healthcare provider will then extract amniotic fluid for testing. The healthcare provider will use an ultrasound to ensure that they do not harm the baby with the needle. There is a risk of damage or infection in the baby when this procedure is chosen, thus it is typically only recommended during high-risk pregnancies, including those that have a positive triple screening test or advanced maternal age.
The CVS test is actually considered more risky than an amniocentesis. Whether or not you decide to opt for genetic testing is completely your decision. You may be pre-disposed to certain conditions. Many parents want to know the possibility of a potential problem ahead of time, so they can prepare themselves mentally for what is to come in the weeks to follow. It is important that you go into any testing situation fully informed and aware of the potential benefits and risks.
Remember that testing is not without its associated errors and false positive results. Many babies that have positive test results are born perfectly healthy. Be sure you discuss your situation with your doctor in detail before deciding on any procedures that may be suggested for you. Some women will opt to forgo any genetic screenings even if a triple marker test indicates the potential for a birth defect or genetic abnormality. Have confidence that you can make the decision that is best for you and your baby, and be sure to lean on your family and friends for support when necessary.
The evidence continues to mount regarding the value of breastfeeding for both mom and baby. Breast milk provides developmental, nutritional, and immunologic benefits to the infant that cannot be duplicated by formula feeding. With the development of iron-fortified formula in the late 1950s, breastfeeding rates began to decrease as formula feeding gained popularity. Since that time, breastfeeding rates have been increasing but they have not yet reached the goal set by the U.S. Public Health Service, which is-for 75% of mothers to initiate breastfeeding after delivery.
