8 weeks pregnant, your baby’s heart has already been beating for 3 weeks! Fetal development is rapid, and a lot is happening with your belly and body too. Can you still button your jeans? Many women may find it difficult now.

Let’s take a look at your baby’s development, how big your baby is, pregnancy symptoms, what’s happening with mom’s body and belly, and what a pregnancy diary may look like this week.

Week 7 | Week 9

8 weeks pregnantPin

When you are 8 weeks pregnant, your baby’s heart has already been beating for 3 weeks and his or her toes and fingers are being formed, as you can see in the photo below.

Your uterus is expanding rapidly, which may lead to some cramping. Mild cramping is normal, but if you notice any bleeding, contact your health care provider!

What to Expect When 8 Weeks Pregnant

How Many Months is 8 Weeks Pregnant?

When you are 8 weeks pregnant, you are still in your first trimester and month 2 of pregnancy. You still have 7 months to go.

There is often confusion when it comes to counting the weeks and the months of the pregnancy. As you know, pregnancy lasts 40 weeks (or 280 days). We also say that it lasts for 9 months.

There is a discrepancy if you think that one month has 4 weeks. That way, it seems that pregnancy actually lasts 10 months. However, a month doesn’t last for 4 weeks, but 4.3 weeks on average. Every month (except for February) has 30 or 31 days. That is why we say that pregnancy lasts 9 months, although it lasts a bit longer, something like 9 months and one week.

The other source of confusion is the difference between how many weeks/months pregnant you are and what week/month of pregnancy you are in.

Let’s try to explain it this way:

Imagine yourself literally walking through your weeks (day 1, day 2, …, day 7). Let’s say you are now exactly 7 weeks and 3 days pregnant. That means you are currently pregnant for the full 7 weeks plus 3 more days, which means you are in your eighth week. Once you reach 7 weeks and 7 days, you reached the finish line for week 8. You are now full 8 weeks pregnant and are entering your ninth week.

The same is with months. To reach a certain month of pregnancy, you need to complete all the weeks in it fully. If you are in your 5th month of pregnancy, it means you are pregnant for the full 4 months (the months you fully completed), plus a certain number of weeks. After you complete all the weeks in month 5 (4 months + 1/2/3/4 weeks), you will be 5 months pregnant and enter your sixth month.

To make it easier for you to understand, we wrote a post on counting pregnancy weeks and months.

Your Baby’s Development

How Big is my Baby at 8 Weeks?

The fetal age of your baby is now 6 weeks.

The little embryo is now the size of a pinto bean or a raspberry, measuring around 0.6 inches (1.6 cm) in length.

He or she weighs a whopping 0.04 ounce (1 gram).

Although this may not seem large even at 2 months of pregnancy, your body is rapidly expanding to try and accommodate the growing child inside of you.

What Does my Baby Look Like at 8 Weeks Pregnant?

what does baby look like when 8 weeks pregnantPin

As you can see in the picture , your baby still does not look completely like a human, but he or she sure is getting there! The baby’s body is straightening, and the embryonic tail is almost gone.

You can now clearly see arms and legs, and even little fingers.

And cool – the nose tip is being formed!

Twin Pregnancy Ultrasound ScanPinThis week, an ultrasound would reveal if you are carrying twins or not – as in the picture.

Only 1 in 60 are twin pregnancies, but heredity and mom’s age may increase your chances of a twin pregnancy.

Your first ultrasound scan will let you know. If you are pregnant with twins, or suspect you are, you might enjoy reading this interview with a twin mom.

 

 

Fetal Development in Week 8

Besides looking a bit more like a human, other amazing things are happening this week with your baby’s development.

A fascinating milestone is that it is now possible to register brain waves in your little embryo.

As the eyelids and ears are still forming, the eyes are still placed very wide on the sides of the head but will center themselves out in time. This week, the retinas in the baby’s eyes are beginning to form.

Fingers and toes have now begun to branch off of those arm and leg buds that have been developing these past few weeks, even though you would see more of a webbed look to them for now. Both the arms and legs can extend forward and bend at the elbow that is also now present.

Your baby’s torso is expanding and straightening out in order to make room for all of the activity that is going on.

The intestines are starting to develop, but because there is not enough room for them in the baby’s abdomen, they move into the umbilical cord. They will move into the abdomen when there is enough room.

The tubes that lead from the throat to the lungs branch out. Your baby’s heart is beating at a rate of about 150 to 170 times per minute, and the chambers of the heart are now visible with an ultrasound.

You’ll find a number of great fetal development videos in this post.

Mom’s Body when 8 Weeks Pregnant

The Belly

You might be able to notice a slight difference in how your clothes fit now. Exciting! Even though you can still probably fit into that favorite pair of jeans, they may be snugger, and you won’t be wearing them for much longer.

By strategically dressing, you could probably still hide the small life growing within you if you are still unsure about letting the world know of your exciting news. But it certainly gets more difficult with every pregnancy for most moms. The stomach muscles are more stretched in your second pregnancy (and on), and the baby bump is likely to show earlier.

Pregnancy Symptoms

8 weeks pregnantPin8 weeks pregnant, it is perfectly normal to feel moderate cramping and discomfort from your expanding uterus, but if you start to notice vaginal bleeding, seek professional medical advice. Mild spotting can be perfectly normal, but if it persists, it could be a sign of problems.

You are probably aware of the risks of miscarriage during these first several weeks of pregnancy. However, if a live embryo has been seen in an ultrasound at around 8 weeks pregnant, the risk of miscarriage is significantly reduced.

You might be experiencing one of the most known early pregnancy symptoms—morning sickness. Although the name suggests otherwise, morning sickness might appear at any time during the day. Try to eat smaller meals, but frequent. If you are experiencing severe nausea and it’s hard to keep the food down, try to find foods that work for you. Although you might stress about not eating a variety of healthy foods, at this point, it is most important that you eat something that won’t make you throw up.

Because of the hormones, some women also experience food and smell aversions.

You are probably fatigued, which is also normal. Try to rest as much as possible and sleep when you can. The good news is that this exhaustion usually goes away in the second trimester. But then it comes back near the end of the pregnancy. 😊

Don’t be surprised if you feel bloated and experience gassiness. It is the result of the hormones that are relaxing your muscles, which includes the gastrointestinal tract. It is uncomfortable, we know, but it will pass.

Your breasts might have started to grow. It is different for every woman, and while some might continue wearing their pre-pregnancy bras almost the entire pregnancy, others will have to buy bigger ones as their breasts might go up a cup size or even two.

As we always emphasize, every pregnancy is different, and not every woman experiences the same symptoms. Some women experience certain symptoms earlier, some experience them later, while some won’t experience them at all. Every pregnancy and the way a woman’s body reacts to it is unique.

Things to do and buy this week

Eating healthy will help your baby develop well both now and in the future.  To learn about how to eat to promote your baby’s health, click here.

At 8 weeks, it is time for your first prenatal doctor’s visit. You will probably give a urine sample, and your blood will be drawn to check the hormone levels. You will most likely also have your first ultrasound, where the doctor will check the baby’s growth and heart rate. If you have any concerns or questions, talk to your doctor about it.

Many new parents will wait 12 to 14 weeks before they announce their pregnancy, while others cannot hold their secret for long and let everyone know right away. When do you want to tell? With my first baby, we waited until after week 12. With our second, we told everyone the day after we had a positive pregnancy test! :-)

Your pregnancy can affect many decisions that you have previously not considered, such as taking holidays. Vacations out of the country often require immunizations, and some can be harmful to some expecting mothers. Make sure to check with your medical provider before planning any long trips to avoid unnecessary health risks.

If you haven’t bought any pregnancy books yet, now is a great time! I bought a pregnancy diary (and you can read what I wrote in it here below), as well as a general pregnancy health book and a picture book. (Links to Amazon so that you can check them out):

8 Weeks Pregnant: What's Happening in Week 8 of Your Pregnancy?

Diary of a Daughter


What’s it really like being 8 weeks pregnant…? Here’s a true diary from an 8 weeks pregnant mom (Me..!)

I’m beginning to be very tired and nauseated in the evening. (Morning sickness – who came up with that name.) Frying food makes me feel like throwing up. My stomach is kind of large and bloated.

But none of this is really important because two days ago I had an ultrasound… I’ve seen my baby! It made me cry. A tiny little embryo with a beating heart. Such a miracle!

    I don’t see an umbilical cord in the picture above. How can the baby survive without it?
