Twin Pregnancy Week 10: Symptoms, Baby Size, Body Changes & More

10 Weeks Pregnant With Twins

When a woman completes ten weeks of pregnancy, her belly starts showing considerably, and many people with sharp eyes might deduce the news before she can officially announce it. Being pregnant with multiples or twins can put you on a different path of pregnancy progress altogether. Most twin pregnancies are discovered during an ultrasound much before the 10th week. If you’re a pregnant woman expecting twins or multiples, this is the time to celebrate and make an official announcement to your friends and relatives if you haven’t done so already. Many first-time parents are anxious about miscarrying their babies in these initial weeks. With those fears behind you now and the belly showing itself pretty evidently, you can now look forward to the golden phase of pregnancy with twins at 10 weeks.

Baby Growth at 10 Weeks

Being pregnant with twins means more frequent checkups, bigger belly size, weight gain and even earlier delivery. If a previous couple of weeks has had a large amount of growth in length and size, this week is usually a little calmer. They usually expand by about an inch, which is still a good amount. Their weight, however, undergoes a substantial improvement, sometimes doubling itself from the previous week.

Around the 10th week, most babies reach a stage where their core organs have achieved proper development and formed fully. This can allow the process to focus on their growth as human beings. Babies will move around quite a bit now that their legs and hands are flexible and free, leading them to flail about independently.

Bone growth is on track, with the cartilage growing quite rapidly. The teeth development stays as it is, growing properly below the gums. If you could observe your child with a magnifying lens, you could spot minuscule fingernails beginning to appear on the toes and the hands, along with light, lush hair growth all over the body. Male babies start testosterone production by this stage.

What Is the Size of the Babies?

From seeds and peas to grapes, your babies tend to have one of their most significant growth in size around this week. The 10th week has your tiny ones in the womb as large as strawberries with a length of around 3-4 centimetres when measured from their head to the butt. Some doctors might choose to commence measuring baby weight around this week, while others might wait for a couple more since the babies would not be heavier than 5 grams each.

Common Bodily Changes

As the twins or multiples within your womb start putting on weight and increasing in size, the same will show on your body in various ways.

  • The increase in waistline and breasts becomes a little more apparent. This can result in most of your previous dresses failing to fit you well.
  • Stretch marks could become more visible around your abdomen and thighs, usually, the areas where the weight gain is the most.
  • The presence of multiple babies in the uterus ends up being harder on the veins that help circulate the blood to the legs. Due to hormonal changes and increased blood volume, many women observe blue-coloured veins becoming visible. This phenomenon can also be seen in your breasts.
  • The hormone production stays strong, and with a twin pregnancy, the human chorionic gonadotropin or hCG production is always on the stronger side, combined with an increment in blood volume. Together, these result in the skin receiving a lot of blood than before, causing it to flush and secrete the natural oils. In many women, this constitutes a lovely magical glow, leading to skin that is shinier and smoother.

Symptoms of Twin Pregnancy at 10 Weeks

Your body will undoubtedly show signs of having twins at 10 weeks in various ways. Many symptoms are pretty evident on that front, although most of them seem to start being less frustrating over time.

  • You might expect chronic nausea and morning sickness to start reducing by now, but some women tend to experience it for a bit longer. If you turn out to be one of those unfortunate ones, have faith. All of those frustrations are on their way out soon.
  • HCG is released by the placenta and causes mild nausea. However, there is a condition called hyperemesis gravidarum, where there is extreme nausea and vomiting during twin pregnancy. It can also cause a weight loss of more than 5 per cent of the total body weight.
  • The increasing size of the uterus and the jostling of internal organs within the abdomen to make space for themselves can pressure the muscles in that region, especially the ligaments. While some women experience it just as a discomfort, the presence of multiples can result in ligament pain, which can get worse for some.
  • Carrying twins or triplets or even more is not an easy job. Your body has to spend all its energy to make sure your daily functions carry on unabated. This expense of power can lead you to be exhausted, and it is fine if you choose to rest more often than usual.
  • The increased hormone levels and blood flow do not just affect veins’ visibility. They can also make you experience mood changes. 
  • Since the blood flow is increased and reaches all parts of your body, it stimulates those regions, including the vagina, resulting in a discharge of sorts, which can even look a little weird than usual. The elevated estrogen levels cause the discharge to occur, and it is a natural way for the body to keep your vagina clean and remove any harmful bacteria.
  • You may have filler breasts right from the beginning. Milk glands and fatty tissues in your breasts grow in preparation to feed not one but two babies! It might soon be time to shop for a larger, more comfortable bra.
  • Your centre of gravity may shift, and your posture may vary as your uterus and belly grow, straining your spine. To assist you in relieving the discomfort and build up your back muscles, you can engage in some doctor-recommended stretches or exercises.
  • A twin pregnancy can also increase the risk of postpartum depression because it takes more time for the mother to adjust to the post-delivery schedule.

Family members tend to coerce many pregnant women into eating more than they feel fit. It is natural to feel hungrier than you usually do, and it is just as important to meet a calorie count of around 600 extra calories or a bit more, as suggested by your doctor or nutritionist. Such an elevated calorie count is usually satisfied by the random snacks you have throughout the day. Weight gain is good, as long as it is natural. Anything that is extra can put extra pressure on the body to maintain health and cause you to be overweight after delivering the children.

1. Can I Feel Twins Moving at 10 Weeks?

No, it is unlikely to feel twins moving at 10 weeks of pregnancy. Fetal movements are typically felt around 18 to 25 weeks after pregnancy. Any sensations in the abdomen during the first trimester are likely unrelated to fetal movement. In addition, during the early stages of pregnancy, the size of the uterus is still relatively small, and the babies themselves are tiny and surrounded by amniotic fluid. These factors make it less likely for you to feel their movements at 10 weeks.

Taking care of twins at ten weeks in the womb is not as difficult as it sounds since the tricky period of the initial phase of embryos has been successfully navigated. Your babies will now be set to grow rapidly, and so will your body. Breathe deeply, for the best times will soon come your way.
