13 Weeks Pregnant with Twins

  • Announce your twin pregnancy to the world (or wait until you’re comfortable). Traditionally folks wait till the second trimester to tell the universe, and you may want to join them. Some folks are very clever coming up with pregnancy announcements, while others simply just blurt it out in casual conversation. It’s up to you to decide how, when, and with whom you share the news, but we are glad you are sharing it with us 🙂 
  • Ask your social network for referrals to other parents with twins you can talk to or meet in your area. Time to start digging in and find a local twins club and even start researching local pediatricians. Your local moms group (twin specific or not) is a great place to start with referrals.
  • Join the Twiniversity Parent-to-Parent Mentorship program to find a mentor! Now is the time. We can match you up with an experienced mom or dad who will help you every step of the way. Sure, they may not live across the street from you, but thanks to this fancy system called the interweb, we can connect moms and dads around the globe. So join today.

twin pregnancy concerns

Concerns other Twiniversity moms had when they were 13 weeks pregnant with twins

  • Twin-to-twin Transfusion Syndrome
  • Just health, and hoping that they don’t come too early.
  • Big “life” things – needing a bigger house, bigger car, how we’re going to afford it all.
  • Worry that I’m not eating right.
  • Worry that I’m going to get huge.
  • Can I really afford to go back to work and pay for daycare for twins?

doctor questions

Questions Twiniversity moms had for their doctors when they were 13 weeks pregnant with twins

  • What testing should I expect?
  • Do I need to have any special considerations for exercise?  
  • Can I do prenatal yoga?  
  • Do I have any lifting restrictions?
  • Can I have normal sex?
  • What can I use to ease constipation?
  • Do you ever try to deliver vaginally or always c-section?
  • At how many weeks do you induce?  
  • What type of twins do I have? Di/di, mono/di, or mono/mono?

Typical tests that are done  

Chorionic villus sampling (or CVS) is an optional test and is typically offered between weeks 10-13 of pregnancy, when the test results might have a significant impact on the management of the pregnancy. Chorionic villus sampling can reveal whether a baby has a chromosomal condition, such as Down syndrome, or other genetic conditions, such as cystic fibrosis. Ultimately, the decision to have chorionic villus sampling is up to you. Your health care provider or genetic counselor can help you weigh all the factors in the decision.

Typically, first trimester screening is done between weeks 11 and 14 of pregnancy. First trimester screening is a prenatal test that offers early information about a baby’s risk of certain chromosomal conditions — Down syndrome (trisomy 21) and extra sequences of chromosome 18 (trisomy 18). First trimester screening includes a blood draw and an ultrasound exam.

what to do when you're having two

An excerpt from Twiniversity founder Natalie Diaz’s book, “What To Do When You’re Having Two

what to do when you're having two

Twin mamas suffer from many of the same problems as singletons, ranging from simple discomforts to life threatening emergencies.  We are just so lucky that the discomforts start earlier and are often more severe. Count yourself doubly blessed for these all too common pregnancy complaints.


The number one complaint of all twin mamas is fatigue.  If you’re someone who used to burn the midnight oil and now you’re passing out on the couch at 9, just throw in the towel, man.  Don’t feel bad about it. I always laugh when I hear women who are carrying twins ask, “Why am I so tired?” You’re building not one, but two humans in there.  That’s why. Go to bed already. Go to bed now. You have my full permission…
