Twin Pregnancy Weeks 6 and 7: What to Expect

Sharing is caring!

Twin Pregnancy Guide Week 6 and 7

At 6 and 7 weeks pregnant with twins, chances are, you still don’t know that you’re expecting twins.

How crazy is that?? You are growing and forming two babies inside of your womb, and you don’t even know it yet!

You can read an excerpt from my pregnancy journal at the bottom of the post and see that despite not realizing that it was twins, I could tell that there was something drastically different about this pregnancy.

My first pregnancy was a boy, and I speculated that my 2nd pregnancy was a girl because I felt so. much. worse.

Little did I know that the reason I was feeling awful was because I was expecting, not one, but TWO… identical twin girls!

In this post, you can read about what to expect in a twin pregnancy, as well as twin fetal development in weeks 6 through 7.

Symptoms at 6 and 7 Weeks Pregnant With Twins

By 6 t0 7 weeks pregnant with twins, you will likely be feeling pretty miserable.

I’m not going to sugar coat it.

Being pregnant with twins is really, really hard.


Morning sickness is a symptom that many pregnant women experience. It’s the feeling of nausea and vomiting that occurs, despite it’s name, 24/7. Morning sickness is not actually limited to the morning.

Morning sickness is most likely caused by pregnancy hormones, and guess what? When you’re pregnant with twins, you experience twice as many hormones flooding through your body.

Twice as many hormones means twice as much morning sickness.

Sorry mamas. Twins = double the giggles and double the love… but also double the pregnancy symptoms.

Relentless Fatigue

You will feel fatigued for pretty much the duration of your twin pregnancy, but it’s often the worst during the first trimester.


Your body is working SO SO SO hard to create and grow these little babies!

Not only is it creating two babies, but depending on the type of twins you’re having, 2 sacs and placentas as well.


Ugh, those darn hormones again. First trimester of twin pregnancy will have you feeling all the feels. Sad? check. Mad? Check. Downright crabby and moody? Check, check.

Take deep breaths, and apologize to your partner when you snap at them.

Food Aversions

Food aversions are another very common first trimester pregnancy symptom and usually fades away by the second trimester.

Listen to your body and don’t eat foods that don’t sound good! It could definitely trigger your morning sickness.


Just as you have food aversions, you also might experience food cravings.

If you’re lucky, you’ll crave healthy foods such as fruits and vegetables. If you’re like me, you’ll crave carbs and sweets!

Whatever you crave, try to listen to your body, within reason.

Pica is when you crave things that aren’t actually food, such as dirt or chalk. If you ever experience these cravings, consult with your doctor ASAP!

Heightened Sense of Smell

A heightened sense of smell is a big factor in your food aversions. When everything smells SO STRONG, it’s hard for food to sound appetizing!

There were certain foods I couldn’t stand my husband cooking, especially meat and eggs! I would stay in our bedroom with towels in front of the door!

If I had to go downstairs for something, I’d carry a cloth with a few drops of peppermint oil under my nose and that helped tremendously.

Excess Saliva

You might notice that you produce more saliva while pregnant. It’s such a weird pregnancy symptom, right?

Ptyalism, the medical term for drooling, is a result of your hormone levels rapidly changing. It’s also common with morning sickness and nausea.

Period-like cramps are common and totally normal in the early stages of pregnancy. It can be nerve-wracking, but try not to worry unless it hurts worse than a PMS cramp.

If at any time it feels worse than that, call your doctor immediately.

Tender Breasts

Your breasts are probably tender and very sore. The culprit? Extra blood flow. Your body is getting a head start on breastfeeding!

Twin Fetal Development at 6 and 7 Weeks

At 6 weeks, your babies are about 1/8 inch and less than .04 oz. In fruit terms, they are the size of pomegranate seeds

By 7 weeks, they are .5 inch and less than .04 ounce. They are now the size of small blueberries.

Between weeks 6 and 7, your twins will develop fetal heartbeats. This means that if you go in for an early ultrasound, it is possible that they will detect two heartbeats!

My Twin Pregnancy Experience at 6 and 7 Weeks

My entry for 6-7 weeks read:

Week 6: Definitely experiencing a heightened sense of smell. I’m extremely moody, and FATIGUED. The fatigue comes and goes, but when it comes, it COMES.

Week 7: Food aversions like crazy. I can hardly eat anything and am constantly nauseous. I don’t actually throw up, but have the urge to throw up 24/7. Symptoms are so much more intense than with Theo, makes me speculate that it’s a girl!

Fatigue is big time.

I feel as if I’m drugged! I can barely keep my eyes open to play with Theo. We have never used screen time since he’s not even two yet, but I feel like we may need to start!
