At 12 weeks pregnant with twins you may still be experiencing some of the same symptoms you were in early pregnancy, along with some new ones, although some might ease up as you enter the second trimester. Some symptoms include pregnancy sickness, constipation, weight gain, headaches, skin changes, and increased discharge. At this stage, your babies have faces, organs, and limbs, and will continue to change and develop as your pregnancy progresses.
By this time, you’ve likely seen your healthcare provider and know you are pregnant with twins. At a 12-week ultrasound, you will be able to see your twins if you haven’t seen them already. Your babies are now developing rapidly and taking up your entire uterus. You will be entering into the second trimester of pregnancy soon.
At this time, you may still be experiencing some of the same symptoms as earlier on in pregnancy, although as you soon as you enter your second trimester they may ease up. However, there are new symptoms that will likely develop as pregnancy continues.
At 12 weeks pregnant, you may still be experiencing pregnancy nausea, and possibly vomiting. You may feel pregnancy sickness even more intensely with a twin pregnancy. The good news? For many women, pregnancy sickness eases up in the second trimester.
Many women experience specific food cravings or a new dislike for a specific food. The types of food pregnant women crave or can’t stand varies from person to person. While some crave pizza and French fries, it’s also perfectly normal to crave veggies and fruit. Remember, it’s temporary, and your cravings will return to normal soon.
Because the pregnancy hormone progesterone slows down your digestive system, you may have constipation and struggle to have bowel movements. Walking, drinking water, and eating fiber can help prevent constipation, but talk to your provider if you’re unable to have regular bowel movements.
As your babies grow and your uterus expands, pressure is being placed on your bladder, making it so you need to pee often. Pregnancy hormones and an increased amount of blood flow throughout your body also increases how much fluid is filtered through your kidneys. Limiting how much coffee, tea and soda you drink, cutting back on beverages before bedtime, and emptying your bladder when you do pee can help.
Weight gain is important and expected during pregnancy, and eating well will help ensure you and your baby get the nutrients you need to grow and develop. While each woman is different, weight gain expectations are higher for women who are pregnant with twins compared to women who are pregnant with a single baby.
The increase in hormones throughout your body, as well as a normal increase of blood volume during pregnancy may cause headaches. Depending on the cause and type of headache, there are some things you can do to ease the pain, like avoiding any known headache triggers, taking a shower, and applying a cool compress to your head.
As blood flow to your uterus increases to support your baby, you may have decreased blood pressure when you stand up, switch positions, or stand in one place for too long. This can cause dizziness. Talk to your provider if dizziness becomes more serious or frequent than you’re comfortable with.
While backaches are more common later in pregnancy due to the increased weight of your babies, they can also occur at the beginning of pregnancy due to loosening joints. This is all thanks to the changes in your hormones – and your expanding uterus.
It’s normal to have more vaginal discharge during pregnancy. This is normal and due to an increase in estrogen. However, consult with your provider if you have green, yellow, or thick cheese-like discharge, if you have foul smelling discharge, or if your vaginal area is red, itchy or irritated. Any of these things could be signs of an infection or problem.
Your babies are growing and developing very quickly at this stage of pregnancy. They have faces, limbs, and organs now and they’re taking up your entire uterus, which can now be felt by your provider above your pubic bone.
Your babies’ heads are developed and their facial features are beginning to form at this stage. Around this week, their eyes move closer together and ears move toward their final position on the side of the head. Their eyelids will also form, but still remain closed.
The cartilage in your babies’ limbs, hands, and feet form around this time and their arms and legs grow longer. The cartilage will harden to bones in the coming weeks and soon your babies will be able to make a fist with their hands.
This week, your babies will develop nails on their fingers and toes.
All of your babies’ organs have begun to form by this time and will continue to grow throughout pregnancy. Right now, your babies’ kidneys begin making and secreting urinem, their pancreases begin making insulin, and their livers begin making red blood cells.
Your twin’s intestines are growing but the wall of their bellies are not closed yet, so their intestines are floating outside. Soon, the abdominal wall will close and their intestines will make their way inside their bellies.
Skin has been forming around your babies over the last few weeks and is now developing into transparent layers. Their skin will thicken and develop as your pregnancy progresses, but will continue to be transparent for quite some time.
Your babies’ genitals have begun to form, although you won’t be able to distinguish their genders quite yet. You will soon, though – in a few weeks!
The placenta, or placentas, have now taken over as the main source of nutrition for your babies. The placenta(s) will continue to become larger as your babies grow to make sure they’re getting enough nutrients from your body.
