When you are 7 weeks pregnant, your embryo is starting to get the features that soon will make him or her look a bit human, with tiny arm and leg buds, eyes and a hole for the mouth. The tail is still there, though.

The hormonal changes that occur will make mom tired, sensitive, and possibly nauseated, to mention some of the more common pregnancy symptoms. Eating healthy and avoiding some foods is now very important.

This article will cover your baby’s development, how big your baby is, what month you are actually in, and what’s happening with your body, mom.

Let’s dive in!

Week 6 | Week 8

What to Expect at 7 Weeks Pregnant

How Many Months is 7 Weeks Pregnant?

Counting weeks and months during pregnancy can be quite confusing. What makes it difficult, is because pregnancy is calculated from the first day of your last period. For example, you ovulate at the end of being “2 weeks pregnant”.

When being 7 weeks pregnant, fetal age is 5 weeks, since your child didn’t exist before ovulation.

You are in the first trimester.

And how many months are 7 weeks? This is where it gets a bit confusing! We say that pregnancy is 9 months, but 40 weeks… It doesn’t go together, which is why most doctors don’t talk about months at all, only weeks!

But – you think of it the same ways as with how old you are. (30 years old, once completed 30 years…) You are 8 months pregnant when you have completed 8 months of pregnancy. So when 7 weeks pregnant, you are still 1 month pregnant.

Your Baby at 7 Weeks

What Does my Baby Look Like at 7 Weeks Pregnant?

7 weeks pregnant fetusWhen you consider that your little one has actually only existed in 5 weeks, it is quite amazing how much has already developed! But as you can see, your baby does not look human yet.

However, this week his or her arms and legs are starting to form!

If you were to have an ultrasound, you may notice that your baby still has the resemblances of a tail, but that will disappear in the next few weeks.

If you are curious about what your baby looks like during this early stage of pregnancy, the book A Child Is Born by Lennart Nilsson. has detailed photos of 7 weeks embryos (and from the rest of the pregnancy too), showing the tiny “hands”, “eyes” and much more. It’s a wonderful book!

You can also watch several fetal development videos here.

How Big is My Baby at 7 Weeks?

7 weeks ultrasoundYour baby is tiny! Once you hit 7 weeks, your baby is now the size of a tic tac ranging in length from 1/3-1/4 of an inch long (0.6-0.8 cm).

Even if your baby is growing quickly, his or her total weight is only about the same as an eyelash. :-) Not very heavy yet! And still, your little tic tac is approximately 10,000 times larger than when you conceived. Wow!

Fetal Development in Week 7

Here are some cool development facts about your baby:

  • The brain of your baby is developing at a rapid rate of 100 cells per minute.
  • Your baby’s face is more defined this week than before, with a mouth hole more visible and ear indentations. Your baby’s eyes are wide open now, even though the irises aren’t developed so far and the eyelids are forming.
  • Arm and leg buds are now visible even though they resemble paddles more than human arms. The arms are capable of bending at the elbow now. Don’t worry, you will be able to see full-grown arms and legs in no time at all and feel all of the movement from the limbs right within your own belly.
  • You can also see the umbilical cord now that feeds your baby from the placenta.
  • The heart is beating at about 120 beats per minute – isn’t that magic?!.
  • It is also possible to detect movement of the embryo by ultrasound.
  • By week 7 the trachea and bronchi of the lungs have formed, so preparation to breathe has started.

Mom’s Body When 7 Weeks Pregnant

How Does my Belly Look at 7 Weeks?

Your uterus is now double the size compared to when you first got pregnant and it is expanding quickly.

Your belly is, however not likely to show very much yet. At least not with your first baby.

If this is your second or third pregnancy, you might actually feel that you are already showing. This is a combination of the uterus not shrinking back completely after pregnancy, and most likely, somewhat weaker abdominal muscles.

It is possible that your belly is a bit swollen and you feel bloating. Your belly might also feel a bit hard, due to the growth of the uterus.

Maybe you have also already put on an extra pound or two? This can, of course, also make your belly look a bit bigger, although the typical baby bump is not there yet.

Pregnancy Symptoms in Week 7

Several pregnancy symptoms may now kick in.

You may experience some mild cramping or twinges during this rapid growth time.

Morning sickness is now real for many pregnant women! Unfortunately, the name of this pregnancy nausea is very misleading – morning sickness can occur at any time of the day.

If it helps, research has actually found some benefits of morning sickness that you can read about here. And this article covers which remedies for morning sickness that actually work (and not).

Mood swings  – One of the major effects of pregnancy hormones is experiencing mood swings; you could be ecstatic one moment with the growing life within you, while the next moment you may want to burst into tears at the slightest thing. This is a very normal part of pregnancy and you are not alone with your emotional roller coaster ride.

Weird dreams – The hormones responsible for your moods may also result in weird, vivid dreams at night. Don’t worry if you start to have weird dreams about your child and pregnancy, or even dreams unrelated to anything normal. Anxiety about becoming a new parent can creep into your subconscious and have a direct effect on your nighttime dreams.

Feeling exhausted – It is very common to feel completely exhausted in early pregnancy. How about you? This is again due to all the pregnancy hormones kicking in.

Make sure you give your self plenty of rest, but also time outside. Make sure to drink plenty of water too! But above all – sleep!

Many women go to bed really early in the evening during early pregnancy. They simply need more sleep for a while. This is not going to last your whole pregnancy, so if you can, give yourself some extra sleep now, if you are very tired.

Miscarriage Risk in Week 7

The possibility of miscarriage is still very real, and big stress for many pregnant women. It can be a very difficult time, especially since you have just gotten used to the idea of being a parent.

In most cases, even if you have had one miscarriage before, you are still certainly more likely to carry your baby to full term with no complications.

If you feel very stressed about the situation, ask for an early ultrasound.

If the doctor or midwife can see an embryo with a beating heart and of the right size when 8 weeks pregnant (i.e next week), chances are very high that it will not be a miscarriage. I asked for that in my third pregnancy, and it was a really great relief.

You can find information on miscarriage risk by week in this article.

    This is not a BABY, this is not even a FETUS: this is an EMBRYO and what it most looks like is a deformed tadpo
