12 Weeks Pregnant with Twins or Multiples

12 Weeks Pregnant with Twins or Multiples

Last Updated on

Congratulations for making this far in your pregnancy; you carried your twins or multiples in the womb in the safest manner possible. 12 weeks is not a short time and there’s a reason why the first trimester is considered so important for a pregnant woman. It is one of the most core phases of the foetal growth and you can rest assured that the times of high risk in your pregnancy have come to an end and you can start focusing on making things better for you and your babies.

The Growth of the Babies at 12 Weeks

Your babies will resemble little plums by the 12th week, and they underwent an intensive growth in the past couple of weeks. Their size grows to nearly twice within that period.

Most of the internal organs that are present within a human body are usually developed inside the babies by the 12th week of pregnancy. By that definition, your little ones can be termed as complete human beings in a way. What remains for them is to expand in size and maintain the same pace of growth for their organs as well.

Digestion is not a process that babies need to worry about while they are inside the womb since they get all the nutrients and oxygen in a manner which can be synthesized directly. However, the stomach muscles and the intestines that have been newly formed begin to undergo certain movements, as if trying to check whether their functioning is appropriate.

The presence of bones and cartilages not only gives your children a good structure for their bodies but also sets into motion the development and formation of white blood corpuscles. This is the exact point where the immune system of your twins or multiples begins to strengthen itself.

With most of the organs are completely grown by this time, the neural network of your twins also reaches a milestone where it can sense outer stimuli and respond to it with a series of reflexive actions. Poking your stomach or changing your orientation can cause your babies to respond to it, which will not be sensed by you as of yet.

What is the Size of the Babies?

By 12 weeks, most babies are usually as large as a lime. Twins and multiples might be a bit smaller than it because of less space in the mother’s womb but don’t you worry as they will catch up soon later. Your little ones would be as long as 6-7 centimetres in length, pretty clearly.

Common Bodily Changes

The body changes that occur in a pregnant woman at 12 weeks of pregnancy are not any special as what was present in the previous week. A few areas might undergo a few improvements or further changes.

  • One of the biggest change that will take place inside you will be in your uterus, it will reach a size larger than what was previously present in the week. This change in size makes itself apparent in a slight bulge over the stomach. Usually, this is where your babies would have their heads situated.
  • The increased diet and weight gain in babies will result in your waistline to increase by a good amount. Opting for loose fitting clothes will soon become your preferred choice in the coming weeks.
  • Acidity and heartburn may also significantly increase given that the levels of progesterone will be receiving quite a boost in this week as a result of the growing placenta. This hormone has the side effect of disturbing the proper functioning of a valve that keeps the stomach separated from the oesophagus during digestion. The acid present in the stomach can creep its way out of the valve and cause the feeling of heartburn in a woman.A pregnant woman feels acidic
  • While the boosted blood circulation and the elevated hormones could lend a pregnancy glow to most women, there is also a chance that your skin may worsen with numerous spots, moles, and dark areas. Most of them occur around the chin and temples, which usually go away pretty soon.
  • The darkness of the nipple and areolas become more evident. Similarly, the tiny bumps that are present on the breast have a more pronounced structure to them. All of these are an evolutionary means of assisting your babies with spotting your breast even with a poor eyesight in their infancy.

Symptoms of Twin Pregnancy at 12 Weeks

The signs of a twin pregnancy at 12 weeks will be substantially reduced as compared to symptoms in the previous months. Some other symptoms might introduce themselves, which may not always be a better choice than before.

  • Most women must have noticed that their vaginal discharge increased in the previous weeks and this will increase even more in the coming weeks as well. The thick white discharge is a natural secretion on part of the vagina to keep itself healthy and maintain a proper pH value. Any foul smell accompanied by a weirdly coloured discharge should be examined by a doctor immediately.
  • Just like the discharge, women will tend to notice a few traces or spots of blood from the vagina, though they will be quite small. Most spotting occurs only after sex, which is quite natural. If the bleeding is heavy or if spotting occurs regularly, a doctor’s intervention is highly suggested.
  • You might be taking good care of yourself but even the slight slipups can have strong symptoms in a pregnant woman. One of the worst ones in this regard is recurring headaches. Anything from insufficient sleep to lack of water consumption can trigger these to take place. Make sure you are well rested and hydrated throughout.
  • The blood volume increases a lot through the pregnancy. This needs to be compensated with enough blood sugar to be present in it, along with proper fluids. Any lacking on this part leads women to feel dizzy and have low blood pressure.

Twin Pregnancy – Belly at 12 Weeks

Usually, a woman’s pregnant belly starts becoming visible by this time but some women may not have a large belly at this time and hence they could fit in their old clothes without difficulty. Though the size of the belly is a strong indicator for the progress of the pregnancy, there’s no absolute in that regard as long as the babies are growing properly.

Apart from the belly, there is a lot of expansion in other areas of the body as well, which will make wearing old clothes uncomfortable. The thighs and hips increase in size, making it necessary to opt for loose pants or trousers. Similarly, a swelling and expansion of the breasts can necessitate a larger bra.

Twin Pregnancy at 12 Weeks – Ultrasound

When you observe your little ones in the womb through an ultrasound at 12 weeks, you will see that the internal organs of your babies will have developed completely developed at this stage.

On doing an ultrasound, you will find that your babies will look more like a human being than a vague shape as before. A lot of movement can be observed during the scan, which involves your babies experimenting with their arms and legs, as well as stretching their body while they test their muscles.

What to Eat

Just because the internal organs of your little babies have been developed fully, does not make that you skimp on any kind of food items you don’t like. A balanced diet during pregnancy is of utmost importance and never compromise it, no matter what stage of pregnancy you might be at. Keep in mind that your twins or multiples are still growing and therefore, you should eat healthy foods. Eating foods such as meat, milk products, and rich vegetables is highly recommended. Also, instead of eating fried or canned foods, opt for baked or boiled foods.

Make sure that you consume foods rich in fibre regularly, even in your breakfast. Keep dinners a light affair since a heavy one can make heartburn worse when you go to sleep. Restrict yourself to small and frequent meals throughout the day. Balancing your food with vitamin supplements is a good choice as well.
