Twin Pregnancy Weeks 6 and 7: What to Expect

Sharing is caring!

Twin Pregnancy Guide: 6 weeks pregnant with twins through 7 weeks

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!

I’m often asked, “How did you know you were having twins?” and although I didn’t *know* for sure (because you CAN’T know until you get an ultrasound!), I could tell that there was something drastically different about this pregnancy compared to my previous singleton pregnancy.

You can read an excerpt from my pregnancy journal at the bottom of the post and see that despite not realizing that I was having twins, I knew that something was up.

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 that I was expecting, not one, but TWO… identical twin girls!

Tip: You can confirm via ultrasound that you’re having twins. If you’re having same-sex twins, you won’t be able to tell if they are identical or fraternal twins unless you do a DNA test. If you are having boy/girl twins, they are obviously fraternal.

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.

Twin Pregnancy Symptoms at 6 weeks through 7 Weeks

By 6 weeks pregnant with twins, symptoms will likely be pretty miserable. By 7 weeks pregnant with twins, symptoms will be even stronger and you will likely be even more miserable.

And it will only get harder as you get further into the first trimester.

I’m not going to sugarcoat it.

Being pregnant with twins is really, really hard.

I’m not trying to sound all gloom and doom, I just want you to have a realistic expectation of what you can expect throughout your pregnancy.

Having twins is UNBELIEVABLY amazing! It truly, truly is! You just have to make it through your pregnancy to be able to enjoy your snuggly babies (I mean, just LOOK at them! So worth all the symptoms of twin pregnancy at 7 weeks!)

Morning sickness is a symptom that many pregnant women experience. It’s the feeling of nausea and vomiting that occurs, despite its 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.

I swear by these tummy drops to help with pregnancy-related nausea! They come in a variety of flavors and run around $13 for a package of 32. They seriously brought me SO much relief!

Here is a list of everything I did that actually helped get me through the first trimester of twin pregnancy!

7 weeks pregnant with twins

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. The 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. Try to get plenty of rest and as much alone time as you can, if you need it.

Food Aversions

Food aversions are another prevalent first trimester pregnancy symptom and usually fade 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. Keep some crackers on your bedside table and nibble at them first thing in the morning.

Although I had no appetite, eating small things such as crackers or toast actually helped settle my stomach so that I could eat a full meal.


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.

Important: Pica is an eating disorder that can be triggered by pregnancy. With Pica, 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.

At 6 weeks pregnant with twins, cramping can happen. 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. And, honestly, if it’s something that worries you, just go ahead and call your doctor. If it gives you peace of mind to make a phone call and to check in, make the phone call.

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 Belly: 6 Week Twin Bump

Unfortunately, I don’t have a 6 week OR a 7 week twin belly picture to share. I was too exhausted to take a picture, and honestly, there’s not much to see at this point in pregnancy.

While you may FEEL as if you’re twin belly is huge at 6 weeks, it’s really just lots of bloating as your body gears up to grow.

Picture of mom at 7 weeks pregnant with twins

This is the only picture I have of myself from weeks 6-7 of my twin pregnancy! I was too busy lying on the couch wondering how on earth I was going to survive a 2nd pregnancy with a toddler, and completely clueless that I was actually PREGNANT WITH IDENTICAL TWINS.

My Twin Pregnancy Experience at 6 and 7 Weeks

I highly recommend purchasing a pregnancy journal! While I wasn’t the best at writing lots of details (so. tired), I at least managed to fill out a few sentences each week and it’s really fun to look back on!

My entry for 6-7 weeks read:

Twin Pregnancy 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.

Twin PregnancyWeek 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!
