31 Weeks Pregnant With Twins: Symptoms, Weight & What to Expect
Find out what to expect when you’re 31 weeks pregnant with twins. You’ve been in the third trimester of your pregnancy for a couple of weeks.
Pregnancy diet, exercise & prenatal vitamins
Do what’s possible to make yourself feel good. Go to a spa, get a massage, relax and keep your feet up. Do any kind of exercise you like – as long as you don’t engage in contact sports or horse riding. You still need to take an iron supplement at 31 weeks pregnant with twins.
Pregnancy symptoms & belly pictures
Your babies are getting bigger and that takes a toll on your body. There’s no doubt that it’s hard work carrying two children. Common pregnancy symptoms are:
- You feel exhausted. You may also feel misrable or unwell.
- You may feel like there’s not enough room in your abdomen. Your babies are pressing on your diaphragm, liver, stomach, intestines and bladder.
- You might feel sore – like when you have a bruise. That’s often caused by your babies kicking in the same place again and again. They may have a favorite position.
- Your lower back and pelvis might be tender or sore. It’s common to have muscle tension in your buttocks, abdomen and pelvis.
- Some women feel abdominal pressure. As your twins grow and become heavier, it puts increasing pressure on the muscles in your pelvic floor. If you feel intense and sudden pressure, you should be aware that it can be early signs of labor.
Baby weight & fetal development
Your babies measure approximately 41 centimeters (16.14 inches), when you’re 31 weeks pregnant with twins. The median weight for dichorionic twins is 1730 grams (3lbs, 13oz) and for monochorionic twins it’s 1642 grams (3lbs, 9oz). Look at our estimated fetal weight charts to learn more about how twins grow in the second half of pregnancy. Your children are developing their senses. They can now distinguish light from dark, feel, hear and taste what you’re tasting. The flavors your babies taste inside the womb won’t be quite as strong or distinct as those you taste. Sensory impressions are sent to their brains, stimulating their brain development.
Twin boys & genital abnormality
If you are expecting a boy – or two – their testicles will start to descend into the scrotum a few weeks before birth. When you’ve given birth, the midwife or doctor will check to make sure that their testicles are in the right place, as a part of a newborn’s physical examination. Cryptorchidism – known as undescended testicles – is the most common genital abnormality in boys.
How common is undescended testicles?
Undescended testicles affect about 3-4 percent of baby boys born at term. If your twins are born preterm, there’s a greater risk that one or both of the testicles haven’t descended. Often, the undescended testicles will descend on their own within the first sixth month after birth. If not, they can be helped in place with a minor operation. The operation is important as the condition can affect fertility later or lead to other medical problems.
