Fact Checked Medically reviewed by Tanja Premru-Sršen


Once you get into your seventh week of pregnancy, you are officially in the second month of your pregnancy, which is very exciting! It means that, at 7 weeks pregnant, it is only seven months until your baby gets here!

Another fun fact is that, at 7 weeks pregnant, the embryo is ten thousand times bigger than it was when it first arrived in your uterus! You might not be noticing the changes on the outside at 7 weeks pregnant, but on the inside, your baby is growing very fast and generating new brain cells at a rate of 100 per minute.

The seventh pregnancy week will come with some changes, and it is better to get familiar with them before they happen to feel more ready and more prepared.

Physical pregnancy symptoms during the seventh pregnancy week

As you are slowly getting closer to the end of your first trimester at 7 weeks pregnant, it is expected to experience some physical symptoms on the outside, which are the manifestation of the changes going on the inside. Some of the most common symptoms pregnancy symptoms at 7 weeks pregnant include:

  • nausea and morning sickness
  • vomiting
  • a need for frequent urination
  • mood swings
  • weight gain (a pound is completely normal and expected at 7 weeks)
  • darkening of the areolas and tender and swollen breasts
  • fatigue
  • food aversions and cravings
  • mild pelvic cramping or low backache

Food aversions, nausea, morning sickness

An important note is that the seventh pregnancy week might make certain foods seem repulsive. It can also leave you craving some weird food combinations, such as pickles and tuna fish, as well as suffering from morning sickness, due to the surge of pregnancy hormone (hCG).

The majority of pregnant women start feeling better after the first trimester as they get into the second trimester, but this symptom might also last the whole pregnancy.

Try to avoid any foods and odors that trigger nausea, and satisfy your craving every now and then while keeping your diet as nutritious as possible the majority of the time.

What happens to the developing baby at 7 weeks pregnant?

At the seventh week of your pregnancy, the growing baby inside of your baby bump is about the size of a blueberry.

Even though this sounds so tiny, the actual truth is that your baby is 10,000 times bigger now than at conception, which was just a month ago.

At seven weeks pregnant, the baby’s new brain cells are being generated at the rate of 100 per minute, meaning that most of the baby’s growth is concentrated in the baby’s head.

Your baby’s arm and leg buds will start to sprout and grow longer and stronger. These buds will also start dividing into the hand, arm, and shoulder components, as well as leg, knee, and foot components.

At such an early stage, the limbs will not look even similar to ours, but there is considerable progress!

During the seventh week, your baby’s mouth and tongue will also form. In addition, the kidneys, which are now in place, will start producing urine soon.
