Your Baby’s Growth During Pregnancy – Week 7

Your baby’s legs and arms will begin to emerge by this time. Your baby will have a small tail which is more like an extension of the tailbone. However, this will disappear as the pregnancy progresses. The foetus has almost doubled in size in the past week. Your baby will experience rapid developmental changes. Both the hemispheres of the brain will start forming now. The tiny liver will begin to function by forming red blood cells, till the bone marrow is formed. The digestive organs like pancreas and appendix start to form too. At this stage, your baby may technically be called an embryo.

What Is the Size of the Baby?

Your baby is approximately the size of blueberry by this time. The 7 weeks pregnant baby size is almost a quarter of an inch. There has been tremendous development from the time of conception as your baby has grown a lot since then and will continue to grow and develop as they should. At this time, the growth is mostly concentrated in the generation of brain cells.

Common Bodily Changes

You may not look pregnant, but there are several changes that are happening inside your body. You can expect the following changes at around 7 weeks of your pregnancy.

  • Nausea and food aversions: You may experience nausea and food aversions by this time. Some odours or smells may trigger nausea. On the other hand, you may also find yourself craving for foods such as pickles.
  • Excess formation of saliva: You may notice the formation of excess saliva in your mouth. Try chewing sugarless gum to avoid pooling of excess saliva in your mouth.
  • Changes in the breasts: Your breast size may increase this week. This is due to the increase in blood flow and fat build up around your breast.
  • More frequent bathroom visits: There is an increase in blood flow around your pelvic region because of the hCG hormone, resulting in frequent urination.
  • Skin breakouts or acne: You may also notice acne on your face. This is due to the hormonal changes happening in your body.

Symptoms of Pregnancy at Week 7

There may not be evident physical signs by 7 weeks of pregnancy, but you may notice the following symptoms at this week:

  • You may start to feel sick in the mornings (nausea and vomiting). You may also experience headaches and other pains. Fatigue and lethargy may be noticed too.
  • Your breasts may become tender and the areoles will become darker than usual.
  • You may crave certain food items and develop an aversion for some.
  • You may not fit too well into your favourite pants or jeans. This is not due to weight gain but due to bloating.
  • You may also experience mild pelvic cramping. There might be occasional spotting too.
  • One of the important developments in your body during this time is the development of your mucous plug. The mucous plug helps seal the cervix and protects the opening of the uterus till the birth of your baby.
  • You may find yourself battling with changing moods. This is due to the changing hormones in the body.

Belly at 7 Weeks of Pregnancy

Your belly at 7 weeks won’t give away that you are pregnant even though you might be experiencing a lot of changes in your body. So you will have to wait for some time to be able to flaunt your baby bump. All that you feel is bloating around your belly by week 7 of your pregnancy. Most mothers-to-be start to show the baby bump by the middle of their second trimester. However, if you are carrying twins or more babies, then your belly may start to show earlier than the standard time.

Ultrasound at 7 Weeks of Pregnancy

By week 7, you may be ready for your first ultrasound scan though many doctors may wait till 8 to 10 weeks of pregnancy for the scan. You doctor will ask about your medical history and the recommendation of your doctor. An ultrasound will help the doctor take various measurements of your baby, and determine the development of the foetus. Though your baby is too tiny for you to spot in the ultrasound scan, the embryo is generating almost one hundred brain cells per minute. The embryo is developing its heart, kidneys, arms and leg joints. If you are carrying twins, the scan will show two gestational sacs in the ultrasound scan. You will also be required to give urine and blood samples for various tests.

The blood samples of the mother carrying twins or multiple babies may show increased levels of hCG hormone, this increased levels of hormone may result in morning sickness.

What to Eat?

It is very important for you to eat a healthy and balanced diet in pregnancy. Your 7th week pregnancy food should include the following:

  • A healthy mix of green, red, yellow and orange vegetables is a must include in pregnancy diet. Have 3 to 5 serving of vegetables in day. Spinach, broccoli, tomatoes, red peppers, pumpkin, carrots, yellow peppers and corn are some of the fresh vegetables you may include in your diet.
  • It is suggested to opt for fresh fruits over canned or preserved food as preserved food may contain harmful bacteria which can be harmful to you and the baby. You should take 3 to 4 servings of fresh fruits in a day.

  • Consume milk, cheese, yoghurt and other milk products to meet the calcium demands of your body. Around 3 servings a day is recommended.
  • You should include 2 to 3 serving of protein in the form of eggs, meat and poultry in your diet. Lentils, beans, seeds and nuts are excellent sources of protein for the vegetarian moms-to-be.
  • You should opt for whole grains instead of refined food products. Whole grains provide fiber to your body. It is suggested to have 3 serving of whole grain food items in a day.
