8 Weeks Pregnant

So you’re eight weeks pregnant…

The second month of pregnancy is coming to a close, and it’s probably beginning to feel more real that you are, in fact, pregnant. You may even be gaining weight already, and for the average healthy female there may be a gain of 1-5 pounds in the first trimester before the weight gain becomes more regular further into pregnancy.

You’ll likely be having your first prenatal appointment with an OB soon, in which case you may receive a first-trimester ultrasound to verify the pregnancy is in the uterus and see how far along you are.

This first appointment may involve some various testing, including blood tests (checking hormones, looking for STDs, etc), urine tests (looking at the protein and glucose levels) and possibly a pelvic exam to check for any infections or potential issues.

Baby’s Development

In your eighth week of pregnancy, baby is the size of a kidney bean! Baby weighs about .04 ounces and measures .63 inches long, growing about a millimeter per day.

Facial features are becoming increasingly defined, such as the upper jaw and nose, and eyelid folds beginning to cover the eyes. Just look back at the last week of pregnancy to see the huge change in baby’s shape, including that tail disappearing and ridges developing on the hands, showing where those fingers will be!


7 Weeks Pregnant

So you’re seven weeks pregnant…

The hormones are still increasing, so early pregnancy symptoms may be increasing in severity, you may be developing new symptoms, or maybe you still feel pretty okay. (Remember: Not everyone will have many symptoms or will feel poorly!)

And even though you’re not sporting a baby bump yet, your body is already preparing for baby’s growth, with your uterus expanding. There may be some cramping involved, but beware of bleeding. If you have any concerns, call your doctor. (Though, to be fair, you likely haven’t had your first appointment yet. Now would be a great time to get recommendations and referrals in place for your prenatal care.)

Baby’s Development

In your seventh week of pregnancy, baby is the size of a blueberry! Baby doubled in size from last week, and baby’s brain has grown by a third.

As you can see in the image here, baby has a bit of a tail that will soon disappear, just like baby’s arms will soon transform from the initial paddle-like limbs into distinct arms, hands and fingers. Cartilage and nerves are forming in those arms, which is a process the legs will undergo later.

The umbilical cord is working hard now with blood vessels carrying oxygen and nutrients to and from baby’s little body.


6 Weeks Pregnant

So you’re six weeks pregnant…

The hormones are increasing, so you may be noticing an uptick in the severity of early pregnancy symptoms or the presence of new ones. For example, the pregnancy hormone progesterone may cause you some issues with feeling gassy and bloated.

Be sure to rest when you’re able if fatigue is an issue—you’re growing a human, after all, so give your body some grace as it adjusts to these big changes. And know that more frequent trips to the bathroom are also common, as the pregnancy hormone hCG is routing extra blood flow to your pelvis.

Baby’s Development

In your sixth week of pregnancy, baby is the size of a pomegranate seed! Baby’s growth is continuing to double and now measures .25 inches, and that doubling rate will continue during this week.

Baby is beginning to develop facial features already, including depressions where the nostrils and ears will be, darker spots where the eyes will be formed, and the tongue, jaws and neck are also being created.

Baby may even start some wiggling of the arm and leg buds, which are now growing some muscle and bone tissue. And baby is also covered in such a thin layer of skin that it’s translucent.

By the beginning of this week the heart should have begun beating and would be visible with a transvaginal ultrasound. The heart will be pumping at roughly 100 beats per minute. But if you have an ultrasound and don’t see a heartbeat yet, don’t panic. You may be earlier in your pregnancy than you anticipated and may just need a follow-up appointment to measure for growth.


5 Weeks Pregnant

So you’re five weeks pregnant…

You might just be at the point of having realized you’re pregnant. It’s likely you just missed your period and are starting to feel some symptoms caused by those increasing levels of hormones, like nausea, sore breasts and fatigue.

We’ve got more information for you over on our blog post on early pregnancy symptoms if you’re curious what symptoms to expect and to know if what you’re experiencing is normal.

And adding to that, you might be experiencing no symptoms at all, which is completely okay! You’re one of the lucky ones, and fingers crossed you escape the rest of the first trimester unscathed and free from morning sickness!

Baby’s Development


In your fifth week of pregnancy, baby is the size of a peppercorn! That teeny, tiny little baby is the size of .13 inches from the top of head to its bottom, and growth from here on out will be rapid, with baby doubling in size in one week.

Yet inside that teeny, tiny body BIG changes are happening. Baby is developing major organs, like the heart (the first organ to develop and function), stomach, liver and kidneys, and also developing major systems, like digestive, circulatory and nervous.

And by the end of the fifth week, the heartbeat should be able to be detected via ultrasound! However, being able to HEAR the heartbeat may not come until further in the pregnancy, so don’t be alarmed if your ultrasound technician uses the scan to measure the visible beats per minute versus listening with a Doppler. And at this stage, baby’s heartbeat should be between 90-110 beats per minute, and that will keep increasing until it peaks at 9-10 weeks gestation before slowing a bit in the second and third trimesters.

Now is also a good time to begin taking folic acid, as it helps prevent neural tube defects from forming, and then continue taking that folic acid through the rest of the first trimester.
