If you haven’t taken a pregnancy test yet, now is the time.

At 6 weeks pregnant, more or less every healthy pregnancy should be detectible with a pregnancy test since hCG levels have been on the rise for 4 weeks now. Other signs of pregnancy are often evident, as well.

This article will cover your baby’s amazing development, how big your baby is, pregnancy symptoms, and what’s happening with your body, mom.

What to Expect when 6 Weeks Pregnant

How Many Months is 6 Weeks Pregnant?

At 6 weeks pregnant, you are still in your first trimester and month 2 of your pregnancy journey.

To make it easier for you to understand how to count pregnancy weeks and months, we wrote a post where we explain everything from how the due date is calculated, the difference between the fetal and gestational age, how to know how many weeks/months you are pregnant and what week/month of pregnancy you are in at a certain point.

Your Baby at 6 Weeks

How Big is My Baby at 6 Weeks?

The fetal age of your baby is now 4 weeks. During this week, your baby will be detectable by ultrasound. However, the baby is still very tiny, and you won’t see much detail.

Rapid growth and development are continuing this week as your baby-to-be has grown from a size of a sesame seed to the size of half of a small pea, i.e., just over 1/6-1/8th of an inch (2-4 mm). In only three weeks, i.e., when 9 weeks pregnant, your fetus will be 10 times longer than now.

What Does my Baby Look Like at 6 Weeks Pregnant?

If you are curious about what your baby looks like during this early stage of pregnancy, I really recommend the book A Child Is Born by Lennart Nilsson. I read it and looked at the pictures over and over again during my pregnancies. There was a new edition of this book coming out in 2020 and it is truly amazing!

Fetal Development

Even if you can’t see it, your uterus is full of life and activity. Already in week 10 of your pregnancy, all organs will be created.

The baby’s organs and tissues continue to grow rapidly while new developments, such as the antigen factor that will determine your offspring’s blood type, will be present at the end of this week.

Another body part forming this week is the adrenal cortex, although it will not start producing hormones for several more weeks.

Your baby’s heart is beating right now at a rate of anywhere between 100 and 140 beats per minute, helping to start blood circulation through the body. The heartbeat can sometimes be detected at your medical practitioner’s office with a Doppler device, depending on your little one’s placement, or be seen by an ultrasound if you are lucky enough to have one this early in pregnancy. It is also possible to see if there is more than one embryo growing inside of you.

There are predetermined dark spots that have emerged on your little embryo where the nostrils and eyes will soon develop as well as buds for the ears.

Limb buds that will eventually grow into arms and legs are also forming.

The Belly

Although nothing is still noticeable with a naked eye, when you are 6 weeks pregnant, a midwife can determine your pregnancy by the softness of your uterus.

Pregnancy Symptoms

Be comforted that morning sickness will most likely ease up in your second trimester, and before you know it, your cravings for odd foods will return. You can read about the benefits of morning sickness here.

With all the hormone changes and exhaustion you are experiencing, it is not unusual if you are particularly moody. Many women experience mood swings during pregnancy.

One of the most common early pregnancy signs is the need for frequent urination. So, if it is usually uncommon for you to frequent the bathroom often, that might be one of the signs you are pregnant (if you haven’t determined it yet).

Because of the progesterone, you might also start to experience bloating and gas. Not fun at all!

The color of your areolas may darken at this early stage of pregnancy. You can read more about your areolas during pregnancy here.

Cramping and spotting are not unusual for this time in pregnancy. Cramping is usually a sign that your body is making room for the baby by expanding the uterus and the surrounding tissues. Spotting is usually a result of implantation bleeding. It should be really light and last no longer than two days. If you notice more bleeding than a few drops of blood or experience pain that is more severe or worrying you in any way, contact your doctor. It is always better to check if everything is alright and stay safe. It will also help to ease your mind.

Different changes will happen at stages in each woman’s pregnancy, so do not fear if you are not experiencing one or all of these symptoms immediately.

Slight weight gain may occur for you anywhere from 2-6 pounds in total during this short time, although some women may actually lose weight due to lack of appetite and even frequent vomiting.

Things to do and buy this week

The best way to battle nausea is to cut down your meal sizes into smaller, more frequent portions to help your stomach process food more often rather than digest a larger amount of food less frequently. Drinking an adequate amount of water is also essential for your body since your blood volume increases, and you will need extra fluids. Learn about which morning sickness remedies that tend to work and not here.

Soon you will want to start shopping for those much-needed maternity clothes for the months to come. Be sure to shop around and make sure that the clothes you choose are comfortable, fitting, and easy to take care of. You will not want to iron or take your new clothes to the cleaners each week; you have enough to think about and prepare for in the days to come!
