16 weeks pregnant with twins
At 16 weeks pregnant with twins, you may just be starting to feel your baby move, although it may still be a little while before you feel any kicks. At this point, you’re a few weeks into the second trimester so you might be experiencing round ligament pain, congestion, and heartburn. Your body is pumping a lot of blood to support both you and your baby and your joints may be loosening, which is normal during pregnancy. This week, your twins’ scalp patterns are developing, as is their hearing. They will also start to move in a more coordinated way.
You’re 16 weeks pregnant with twins and in the second trimester of pregnancy! You may be experiencing new symptoms, and are hopefully feeling better overall if you had morning sickness or nausea in the first trimester. Your twins are changing rapidly, and have developed a lot over the last few weeks.
16 weeks pregnant with twins: Symptoms
Early pregnancy hormones rise rapidly in the first trimester, then level off in the second trimester. Because of this, you may now have less of the uncomfortable symptoms you had early in your pregnancy, such as morning sickness. Unfortunately, this isn’t the case for everyone, though. Either way, there are some additional side effects you’ll likely experience as your pregnancy progresses.
. Kicks and fetal movement
Expecting moms usually feel their babies move around 16 or 20 weeks, but you don’t need to worry if it takes a little longer. Moms who’ve been pregnant before may feel movement earlier than first time moms do. Movement from your babies might feel like gas or “fluttering” at first.
. Round ligament pain
The round ligaments that support your uterus (and connects the front part of your uterus to your groin) is being stretched as your uterus grows quickly. This may cause sharp pain when you move. You might feel pain when you stand up, roll over in bed, cough, laugh, or with other movements that might stretch the ligaments quickly. It might feel alarming at first, but is normal and will only last a few seconds. Try changing positions slowly to decrease round ligament pain.
Because you have an increase in blood volume throughout your body, the lining of your respiratory system (including your nose and throat) also receives the extra blood flow and becomes swollen. This will make you feel congested. Some women even have a swelling of their eustachian tube, the tube that connects the throat to the middle ear, which will make your ears feel clogged.
Many pregnant women experience heartburn. This is because the pregnancy hormone progesterone causes your digestive system to slow down, so food stays in your stomach longer than it normally does. Another reason heartburn is common in pregnancy is that your esophageal sphincter (the muscles that close your stomach off to your esophagus) is more relaxed during pregnancy.
. Loosened joints
You will be more likely to experience joint pain later in pregnancy, as your belly grows bigger and you are carrying more weight. However, an increase of hormones in pregnancy causes your body’s joints to be more relaxed, even earlier on. This can make your joints a little more susceptible to injury or overstretching. Take care not to overstretch, and be careful when you’re moving about, as loose joints could cause you to lose your balance and fall.
How your twins are developing at 16 weeks
This week, your twins are moving and stretching, have a circulatory system, and their hearts are pumping blood.
Your uterus is growing and weighs about 8 ½ pounds and has risen above your belly button. It has grown quickly and will continue to grow as your babies get bigger.
Now, your babies’ circulatory systems have developed and their hearts are pumping around 25 quarts of blood a day. This blood is exchanged between you and your baby through the placenta.
. Head and scalp
Your babies’ necks are defined and their heads are now straight. Their heads are large at this time and may be half their size! The hair patterns on their scalps are forming and their faces are starting to become more recognizable. They are able to move their eyes slowly.
Your babies’ ears are now on the sides of their heads, their hearing is starting to develop and they will soon be able to hear sounds. Throughout pregnancy, they will come to recognize your voice as you talk and sing to them, and by hearing you carry on conversations with others.
Your babies’ bones are continuing to develop and get harder and their muscles are developing as well.
You babies are moving and stretching their limbs more freely now and in the coming weeks, they will become even more active. As mentioned above, you may be able to feel movement at this time, although it could still be a while before you are able to feel them move.
