Third Trimester With Twins

You're almost done. Just another three months and you'll be through your twin pregnancy, and the proud mother of two beautiful, bouncing babies.  

Your Twins in the Third Trimester

Your twins are going to start this trimester at around a pound to a pound and a half in weight each, and are going to end it at their birth weights, which should be somewhere between 5 and 7 pounds.

As you're carrying twins, it's normal for your babies to be a little bit early. Around week 37 and 38 are normal, but if there's any other complications, your doctor will be sure to tell you.

Because of this, it's worth familiarising yourself with the symptoms of early labor, just in case. The big three are:

  • Regular contractions that don't stop, and actually hurt rather than just make your belly tense.
  • Thick or bloody vaginal discharge (the vaginal plug.)
  • Your water breaking. It could be a gushing waterfall, it could be a slow trickle. 

Key Things to Expect in Weeks Twenty Five to Forty

  • There's going to be a lot of scans. At least one every two weeks, possibly even once a week. This isn't anything to worry about, though, unless your doctor advises you otherwise. 
  • You're probably going to experience something called Braxton Hick's contractions. You'll know them when you feel them, as a tightness and pressure across your belly and pelvic region. They should only last a minute or two, and should stop if you get up or stretch. It's just your body getting ready to deliver your babies. If they last more than a few minutes though, or keep coming back at a regular rhythm, then call your doctor!
  • Like we already mentioned, twins like to come early. That's why it's best to have everything ready to go, just in case. We recommend having a go bag for your hospital visit ready close to your front door. If this is your first pregnancy, or you need a quick refresher on what to put in it, we've got an article here just for you.
  • Make sure to talk with your doctor about how the big day is going to go. A lot of twins are delivered via caesarian section, but just as many aren't, so this is something to ask about. You'll also want to talk to your OB about your birth plan, pain relief options, and anything specific to your pregnancy.
  • In the last few weeks of your pregnancy, your babies will shift to a head down delivery position, ready for their birth, so don't be surprised if you wake up one morning and find that you're carrying them lower than before. 

What Pregnancy Symptoms Can I Expect in the Third Trimester?

  • Bloating, gas and haemorrhoids
  • Braxton Hicks contractions (see above)
  • Itchy, sensitive stomach
  • Swelling in your legs and feet
  • Low bladder control
  • Fatigue
  • Blurry or affected vision

Now you're into your third trimester with twins, you're almost through your pregnancy. The next few weeks might be tough, but you've come this far, and we know that you've got what it takes to do this! There's going to be a lot going on, so if you want a gentle reminder or a bit of extra support, keep on track with our week by week articles below.
