Fetus Development At 12 Weeks of Pregnancy

At 12 weeks pregnant, you are in the third month of your pregnancy. Only six months remain! Still, have questions? Here is further information regarding the breakdown of weeks, months, and trimesters during pregnancy. So you’ll get to know the fetus’s development at 12 weeks.

Baby’s growth

Approximately the size of a lime, your infant now weighs a whole half-ounce and has a crown-to-rump length of 2 to 214 inches. Your baby has doubled in size over the previous three weeks, even though you’re probably barely showing now.

Fetus development at twelve weeks

Twelve weeks following the last menstrual period, the fetus is fully formed. The sex organs are fully formed, and all organs, muscles, limbs, and bones are present. The infant must now develop and mature. It is still too early for you to feel the baby’s movements, although they will be pretty active.

The Baby’s digestive system begins working

This week marks a pivotal moment for your infant. At 12 weeks pregnant, the Herculean effort of generating new bodily structures is nearing completion, as most of your baby’s systems are fully developed — although there is still much growing.

Maintenance period

During the maintenance period, which lasts for the next 28 weeks, your fetus’ systems develop, and organs begin to function. For one thing, the fetal digestive system is starting to flex its muscles as it begins practicing contraction movements, a skill your peanut will need to push food through the digestive tract after birth.

The bone marrow is hard at work producing white blood cells, which will one day help your child fight infection after she leaves your haven and joins a standard regular group. In addition, the pituitary gland at the base of the brain has begun releasing the hormones that will allow her to have children in a few decades.

Baby’s eyelids

Your infant now has eyelids that are completely developed at this stage. They are not merely closed tightly; instead, they are fused and will continue to be in this state until the latter part of your second trimester.

Baby’s Hands And Movement

At this stage, your infant’s hands are somewhat more developed than their feet, and the baby’s arms are slightly longer than their legs. The newly formed nailbeds are already producing the beginnings of fingernails and toenails, which will continue to develop throughout the remainder of the current trimester until they reach the very ends of the digits.

Even if your baby is beginning to move around a little bit, you won’t be able to feel these movements for a little while longer. Your child’s organs and muscles will continue to develop over the next few weeks, and your child’s size will continue to increase over the next few weeks as well.

The Measurement of the Fetus When It Is Twelve Weeks Old

At the 12th week of pregnancy, the fetus is roughly the size of passion fruit. It measures close to 2.5 inches from the crown to the rump and weighs approximately 0.5 ounces.

Have a look at the diagram down below to have a better understanding of how your child’s development is progressing:

Fetus Development At 12 Weeks of Pregnancy
  • Even though it is still tiny, your child is now completely formed. In terms of size, they are comparable to plums.
  • In addition, the placenta is now completely established, even though it will continue to enlarge for the remainder of your pregnancy.
  • In addition, the placenta is now completely established, despite the fact that it will continue to enlarge for the remainder of your pregnancy. Your blood supply contains oxygen, nutrients, and antibodies transferred to your baby through the placenta. The placenta is your kid’s life support system.
  • Your child is going to continue to develop at a rapid pace from this point forward. Your baby is moving, waving, and dancing even though you can’t yet feel it moving inside you. They are also capable of swallowing.

You at 12 weeks

  • You may have some constipation. Constipation during pregnancy is not universal, although it is relatively common and can be uncomfortable. Occasionally, you may experience abdominal pain or cramps. Caused by constipation, wind, or the expansion of your ligaments as your uterus grows, these are typically nothing to worry about. But if your stomach ache is persistent, severe, or accompanied by bleeding or other symptoms, you should consult your midwife or doctor.

The following is what is occurring with your infant:

  • Your child measures approximately 6 centimeters in length from head to bottom and weighs approximately 18 grams.
  • The kidneys function correctly, as evidenced by the baby’s ability to produce urine and consume amniotic fluid.
  • Your child is practicing breathing movements, as evidenced by the rising and falling of the chest. Additionally, the digestive system is being put through its paces.
  • Your infant now has twenty teeth emerging through their gums.

Advice for You to Consider This Week

1. Make sure you get a flu shot.

It is recommended by the Centers for Disease Control and Prevention (CDC) that all moms-to-be get vaccinated against influenza because all pregnant women are carrying a child at some point during the flu season, which runs from October to May. A recent study found that being pregnant does not increase a woman’s likelihood of experiencing adverse effects from vaccinations.

2. Embrace loose styles.

Your expanding uterus can be felt by your doctor when they touch your abdomen, although you may not have any visible signs of pregnancy. Until you are ready to start wearing maternity clothes, look for items of clothing that are more roomy or flexible. Some examples include maxi dresses with an empire waist, drawstring pants, and lightweight sweaters.

3. Start performing Kegels.

  • The act of forcing your baby out of your pelvis and into the world places a significant amount of strain on you and the muscles that line the pelvic floor, which must expand to previously inconceivable dimensions.
  • Performing exercises that target the pelvic floor can help alleviate some of the discomforts associated with pregnancy and lead to a more reasonable recovery after delivery. Contracting the pelvic floor muscles for up to 10 seconds at a time and aiming for three sets of 20 per day is a good goal.
  • Developing the muscles that support your bladder and uterus might lessen the likelihood that you will experience bladder problems and can alleviate a wide variety of other pregnancy and postpartum symptoms.

4. Stay away from alcoholic beverages.

  • There is a purpose for placing warning labels on the lateral sides of beer, wine, and alcohol bottles. Consuming alcoholic drinks when one is pregnant can result in severe health problems for the mother and the unborn child, including birth deformities and difficulties.
  • Because drinking at any level, even a low one, can result in complications, it is advisable to refrain from drinking until after the baby has been born. However, you shouldn’t be too concerned if you drank a few alcoholic beverages before discovering that you were pregnant.

5. Reconsider the practice of waxing.

  • Shaving might be a breeze, but as your pregnancy continues, you might have problems seeing below your belly or maintaining your balance. Shaving might be a breeze for you right now. While taking a shower will make your hair and skin more pliable, removing it more accessible, you should never shave before you get out of the storm because even a tiny cut can be pretty painful.
  • Waxing and sugaring are both long-term solutions to the problem of unwanted hair. If your skin isn’t overly sensitive, you might want to try them (but make sure to check with your physician first).
  • As for hair removal creams and lotions, bleaches, and other similar products, the judgment is still out on whether or not it is safe to use them during pregnancy, so you may want to put them away until after you have given birth.
