Your Twin Babies at 7 Weeks Pregnant

Right now, your babies are twice as big as they were in week 6, which is amazing. They’re about half an inch long, which to put it in perspective, is about the size of a blueberry.

It’s about this time that your baby really starts to develop externally, with arms and legs lengthening out and dividing into actual hand, arm and shoulder sections, rather than little flappy paddles.

Your babies heads are also developing at an amazing rate. Their mouth is developed now, with a tiny little tongue inside of it, and inside their head, they’re growing new brain cells at over 100 new cells a minute.

The babies are still technically embryos, and they’ve still got tiny vestigial tails, which will slowly shrink down over the next few weeks, until all that’s left is a tailbone.

Twin Pregnancy Symptoms at 7 Weeks

Seven weeks in, you can probably expect to start having pregnancy symptoms, even if you’ve been lucky enough to dodge them so far. Here’s what to expect:

  • Nausea: The hormones that cause morning sickness are flooding your body, which means if you’re going to suffer from morning sickness, it’s going to be strong right now, especially if you’re having twins!
  • Cravings: Food cravings are a completely normal part of pregnancy, and generally your bodies way of getting the nutrients you might otherwise be lacking. If you want to minimise your cravings, then try and eat as healthy and varied a diet as possible.
  • Food aversions: The flip side of the coin. Food aversions during pregnancy are also completely normal, and come at the weirdest times. Some women even have such strong aversions to certain food’s smell, or even the sight of it can set them off. Either way this is nothing to worry about unless it’s completely preventing you from eating. If you’re struggling, go with neutral and relatively dry foods, with minimal flavor and smell. Things like crackers, light cheese and yoghurt are great.
  • Acne: Your body is going through the worst hormonal changes its seen since you were 13 and thought dressing all in black was so cool, you guys, so you can expect a few breakouts here and there. If you’re suffering, or you need it gone, see your doctor and ask them to recommend a prescription, because some over the counter treatments aren’t good to use when pregnant.
  • Mood swings: Not only are you hormonal, but all the changes and different things going on are going to make it doubly difficult to keep your head on straight.
  • More saliva: Yep. This happens. It’s associated with morning sickness and nausea, so if you wake up with a sticky pillow, don’t be too grossed out.
  • Cramping: Your uterus is seeing some big changes, so it’s normal to feel a lot of cramping and aching at this point, as your body makes adjustments.
  • Swollen boobs: We’ve mentioned this one before, but right now, you might be really feeling the pull. Some women have grown an entire cup size by seven weeks in, so if you’re spilling out of your bra, it might be time to get the comfy ones out of the back of the dresser. Some women also start noticing little spots around their areola (the darker bit around the nipple.) That’s normal too, they’re sweat glands, and they’re up to lubricate your nipples.

7 Weeks Ultrasound Twins

At seven weeks, it’s normally quite easy to see if you’re having twins. So if you’re having an ultrasound at seven weeks, keep an eye out for the second baby!

Things to do this week for a healthy pregnancy

  • Start preparing for your first prenatal. Grab a notebook or your phone and make a list of any questions you have to take in with you. Also make a list of any meds you’re on, whether prescription or not, and if you can, write down the date of your last period, so they can get an accurate figure.
  • You could also start taking pregnancy photos, if you haven’t already. The changes you go through can seem incredible when you look back at your twin pregnancy, and the earlier you start, the better.

  1. I feel excited and blessed to be pregnant this I have prayed to God about and I’m also really upset to because the father had chosen to leavE us

    • Maybe the father leaving is a blessing in disguise. It happened to me too. My advice is don’t chase after a man that doesn’t value you and the children. You can have a network of support of friends and family, and have the baby shower, and enjoy those children!

    • You’ll be okay. I promise.
      On my first set, I left the dad. We just didn’t get along.it didn’t take long after to find my true love. He loves the twins like his own it’s amazing. They’re still great men out there. Don’t stress. The twins bio dad is still involved with the children tho. It’ll all work out

  2. Hello u am about 7 and a few days pregnant with twins. Single mother. Very scared and worried. Just needs some tips on whatever that will help me. Thank you

  3. I have a one and two year old and we are 7 weeks pregnant with twins. I have to be honest I AM MISERABLE AND COMPLETELY USELESS. I never had any symptoms with my girls but with the twins I find myself nauseous and sleepy all the time. That on top of the cramps makes me not feel up to anything. My hormones are completely insane. But I have found that lemon water works wonders for energy and curing nausea.

  4. We went for an ultrasound at 6 weeks 4 days, and there were 3 gestational sacs. We found one heartbeat, and we are going back on 5/23 (about 2 weeks later) for another ultrasound. Has this happened to anyone before? Did you have 3 heart beats when you went back??

    I’ve had 4 miscarriages over the last 2 years. We did not do any fertility treatment, and there were 3 sacs in there. I’m anxiously waiting for our next visit.
