Pregnancy Calendar Week 10 – Increase in Your Blood Production

Entering the 10th week put you close to the end of your first trimester. You are now more accustomed to the idea of being pregnant as week by week you are seeing numerous changes inside and outside your body. Here’s what you can expect this week.

Week 10

While you have reached the 10th week of your pregnancy, you are still stuck in the waves of hormonal changes. You are about to enter the second trimester in less than a month, a time when troubling symptoms such as nausea and extreme fatigue will go away completely. This week the embryo officially shuns the title of fetus and becomes an embryo.

Your body this week


You might be hiding your baby bump from the world, but you can’t do that for longer. Your curvy belly will perhaps reveal the secret, thanks to the continuous growth of the teeny tiny inside. So, if you still want to keep the people guessing, then avoid wearing tight and constricted clothes and choose some stretchy waistband and loose-fitting tops.

Your uterus has grown to a size of a softball. You might have added around a kilo to your weight unless you haven’t come across morning sickness. The blood volume this week has increased and you will probably see veins in your breasts and abdomen becoming more noticeable.

Typical symptoms

The increase in blood volume this week also lowers the blood pressure and blood sugar levels. These symptoms can induce sleepiness during the day. Increase in hCG and progesterone is the reason behind this daytime sleepiness. However, progesterone can take this a step further causing sleeplessness at night. Some women might experience strange dreams.

Some other may find difficult to empty the bladder completely. This is because the uterus grows up into the pelvis and can become stuck between the pelvic bony structure and the bladder, causing retention of urine. If this is the case, you must talk to your healthcare provider who will help you drain the bladder completely. This problem though not common can resolve once the uterus becomes 12 weeks old.

Symptoms continuing from past few weeks

While some fortunate women will begin feeling relief from previous symptoms, the majority of them will continue experiencing them.

New signs and symptoms this week

Some women may notice new symptoms in the 10th week. These include:

  • Increased vaginal discharge
  • Foul smelling discharge
  • Low blood pressure
  • Low blood sugar levels
  • Visible veins

Your baby this week

By the time you enter the 10th week, your baby’s vital organs have been developed and working together. Along with the external changes, the internal development is going on with full swing.

Facial development

The tooth buds have started forming under the gums. But those pearly white choppers will only appear when you baby becomes 6 months old. You might be surprised to hear that the head is taking almost half of the total length of the body. It seems like a bulge is on the forehead, but there is nothing to worry about, it simply means the budding brain is growing. The eyelid now fuses to protect the eyes.

Body changes

The fingers and toes have now lost their reptilian or aquatic web-like appearance and formed their individual digits. The nails have also started to grow while the skin becomes less shining. Bones and cartilage are also forming and the small indentations on the legs are taking the form of knees and ankles.


If you are having a baby boy, then his testes which formed last week will start producing testosterone hormone.

Size and appearance

The 10th week baby can be as much as 2 inches long and the end of the first trimester, it can become 3 inches long. If you take a real-world example, it is as big as a strawberry and weighs around 4 grams.

Healthy eating

By this time you would have got serious about your healthy eating habits. Here are few things you can add into your diet this week.

  1. As baby’s brain continues to develop, you should include foods rich in iron such as red meat and eggs
  2. Add whole grains and leafy vegetables to your diet. These are not only rich in iron but also contain other essential nutrients.
  3. Include food rich in vitamin C which helps absorb iron, orange is a great source.
  4. Make nuts your as healthy snack buddy.
  5. Add foods rich in anti-oxidants such as dark chocolate and strawberry. This will also address your food aversion to some extent.

Expecting dads

By the time your wife completes the 10th week of pregnancy, she would be requiring a prenatal appointment. So you want to be with her not just for moral support but also to experience significant milestone (as you will hear your little one’s heartbeat). She would also want you to get along for understanding the doctor’s instructions. This will get you more insight into what’s going on inside her body.


The tenth week is an important moment where you would be deciding to have genetic testing. Your doctor can offer you two options depending on your condition, screening test and diagnostic tests. Where screening test determines the likelihood of birth defects, diagnostic test will tell you with certainty that your baby has genetic disorder.

Screening tests are offered to women under the age 35 years while diagnostic tests are recommended for older women. You will go through:

Nuchal translucency test (NT)

Nuchal translucency screening (NT scan) checks the baby’s for Down Syndrome and other chromosomal abnormalities. This will be done through ultrasound and is part of the first-trimester screening.

Non-invasive prenatal test (NIPT)

Another test for checking genetic abnormalities is known as cell-free fetal DNA test also called as non-invasive prenatal test (NIPT). This is a blood test conducted at around 10 weeks.

CVS and amniocentesis

Other invasive tests include CVS (chorionic villus sampling) and amniocentesis. This will be suggested to women with high risk of chromosomal abnormality based on her risk factors, family history and after getting NTS or NIPT results. The CVS is recommended between 10-12 weeks using an ultrasound in order to determine the location of the placenta. Then the doctor will collect placenta cells by using a speculum inserted through the cervix. These cells will be tested for any genetic anomalies.

For women opting for amniocentesis, they will be suggested to visit between 15-20th week. During this procedure, a small amount of amniotic fluid is extracted to check for certain chromosomal defects.

Tips for the week

You must have gone through your first prenatal appointment, so make sure you follow the doctor’s advice. The doctor might advise you following things:

  1. Continue taking prenatal vitamin and folic acid supplement
  2. Give yourself plenty of rest
  3. Avoid wearing tight-fitting clothes as they might hinder proper blood circulation
  4. Make sure you eat your dinner at least 2 hours before bedtime to prevent heartburn and indigestion from keeping you awake
  5. Include some light exercises to your schedule

The 10th week could be a sign of relieve from morning sickness for some women. At this time, the changes are fast for both you and your baby. While you adjust with your symptoms, keep rejoicing and embracing each moment in anticipation of what’s ahead.
