How big is your baby in week 10?

By the tenth week of pregnancy, your baby attains the size of a strawberry measuring about 1.2 inches in length (from crown to rump) and weighing about 0.14 ounces.

Your baby has now moved from the fetal stage to the embryonic stage. Let’s have a look at the major developments happening in your baby in the tenth week.

Quick fact

In the 10th week, the baby’s head comprises almost half the length of the body, and there’s a bulge in the forehead that allows for brain development (23).

Changes In Your Body In Week 10 Of Pregnancy

In the tenth week, the pregnant belly starts showing up because your baby is growing faster by this time. The belly might not be noticeable for others, but you may find your clothes getting tight at the waistband.

Physical changes likely to happen during the tenth week of pregnancy

1. Pregnancy glow: A fresh, glowing look is noticeable during this period. The increased level of hormones in your body causes oil secretion on your face, which makes your skin look healthy, supple, shinier, and plump.

3. Weight gain: You might notice a weight gain of around five pounds by the tenth week of pregnancy (4). You do not have to worry if you have not gained the recommended weight because morning sickness might actually make you lose weight.
4. Growing breasts: You might notice an increase in your breast size as they start preparing for breastfeeding. Also, the areola becomes darker and larger (5). Also, there can be pain in the breasts.
5. Visible veins: The blue veins become more prominent on different parts of your body as well as breasts as they prepare for the growing needs of the baby.

6. Round ligament pain: You might feel some pains and aches in your abdomen due to the stretching of the ligament to support your growing uterus during pregnancy. In a twin pregnancy, the pain is more intense than in a single pregnancy. Always check with your doctor about abdominal pain.

7. Acne: Active androgen hormones could result in acne breakout on your face (6). If you had a history of acne before pregnancy, you have a higher chance of having them during this period.

8. Vision changes: Increased blood circulation and fluid retention in the body during the tenth week of pregnancy can lead to blurred vision in some women or turn your eyes dry.

9. Pregnancy gingivitis: The increased hormonal activity during pregnancy makes your gums sensitive and irritable. It causes swelling and bleeding of the gum, which is called pregnancy gingivitis. If left untreated, pregnancy gingivitis can increase your discomfort with the progressing pregnancy (7). According to the Centers for Disease Control and Prevention (CDC), approximately 60-75% of expecting mothers experience gingivitis due to the change in hormones.

10. Fatigue: It is normal to feel fatigued during pregnancy because your body is working overtime to meet the demands of the developing baby. You might also experience disrupted sleep during this time.
11. Morning sickness: Nausea and vomiting, known as morning sickness, are common by the 10th week of pregnancy due to hormonal and physical changes. For many women, these symptoms ease, with about half feeling better by the 14th week (2).
12. Increased vaginal discharge: You may notice an increase in vaginal discharge. High estrogen levels and blood flow to the vagina lead to a clear and odorless discharge known as leukorrhea. This process prevents any bacteria from entering inside the uterus. However, if the discharge is tinged with blood and has a foul smell, causing discomfort, or is profuse and watery then call your doctor.

13. Pain in abdomen: You might have cramps and pain in the lower abdominal region during the tenth week as your uterus is growing.

14. Frequent urination: As the uterus grows, it puts pressure on your bladder. Also, the kidneys filter more blood during this time, which makes you pass urine more frequently. Stay hydrated and keep the bladder empty.

1. Backache: The growing uterus shifts your center of gravity putting strain on your back. Also, the pelvic joints start preparing for the childbirth by dilating, leading to back pain. Always check with your doctor about your pain.

16. Headaches: Hormonal changes also lead to headaches. Adequate intake of fluids, nutritional foods, and proper rest will help you get relief from headache during pregnancy. However, headache is an important symptom that you should check with your doctor (8).

Emotional changes

17. Fears: You begin to fear about your pregnancy, the health of your baby, and about anything without reason. You might start having nightmares due to your subconscious worry about the pregnancy (9).

18. Feel stressful: If you are working, you might find it difficult to cope with work pressure and health. Maternal stress may impact your health. Ask for leave if you are not able to adjust to the environment in your office. A break might help you get back to the routine.

19. Lack of interest: All you want to do is sleep. You feel lethargic and find it difficult to move from where you sit. You just want somebody to do everything for you while you sleep and dream.

Make sure to take out some exclusive time for yourself as it can help overcome the emotional changes you might be going through during the pregnancy phase.

However, certain changes might require your doctor’s attention.

Victoria, a mother from Worcestershire/ West Midlands writes in her blog about the symptoms she experienced in the 10th week of pregnancy (as per medical records). She says, “When I wear trousers it feels a bit tighter in a waist area, I feel nauseous and sick, I have more things I don’t feel like eating than cravings, i’ve increased sense of smell driving me mad- feel sick when my hubby uses deodorant, feel sick when I’m in the kitchen while hubby cooks, just generally anything can trigger my sickness. Yesterday I felt sorry for myself, couldn’t stop crying (i).”

When To Call The Doctor?

You must see the doctor if you have:

• abnormal vaginal discharge or foul odor
• bleeding or cramping
• chills
• fever
• severe abdominal pain
• pain while urinating
• severe nausea with vomiting

You should also consult the doctor if you have any infections. Do not take over-the-counter medication.

Can You Get Infections During 10th Week Pregnancy?

You are vulnerable to three most common infections in the tenth week:

1. Urinary tract infections: The higher levels of progesteroneⁱA female reproductive hormone that plays a vital role in menstruation, pregnancy, and breastfeeding. during this period relax the urinary tract, thereby slowing down the flow of urine. This gives room for bacterial growth in the urinary tract (10).

A UTI can also be caused when the intestinal bacteria from the rectum area travel to the urethra making their way into the urinary tract. This can lead to a bladder infection, also known as cystitis. The symptoms include pain or burning sensation during urination, frequent urge to pee, lower abdominal pain, and pelvic discomfort.

Cystitis, left untreated, can cause a kidney infection.

2. Bacterial vaginosis: BV targets the genital tract, i.e., the vagina in a pregnant woman. This infection is associated with a thin, milky white or gray discharge with a foul smell (11).
3. Yeast infections: The vaginal infection is caused due to the hormonal changes, which alter the pH balance and facilitate faster growth of yeast in that area.

The tenth week is not just about changes and infections but is also the time to have the first glimpse of your baby.

Ultrasound At Tenth Week

You are likely to have your first ultrasound scan this week to check the fetal growth. Ultrasound:

• shows the baby’s head.

• detects the fetal heartbeat. In an ultrasound, it is possible to see the heart functioning and the parents may hear the heartbeat that resembles the sound of galloping horses.

• shows the baby sucking the thumb (if you are lucky) (12).

• shows the functioning of internal organs through the baby’s translucent skin.

The ultrasound is done as part of your visit to an OB/GYN, who will also take up other crucial diagnoses.

Other Likely Tests During Your OB/GYN Visit

At week-10 of pregnancy, your obstetrician might recommend a few special tests:

1. Non-invasive prenatal test (NIPT): It is a maternal blood test typically done in the tenth week or later. This test is carried out to screen the mother’s blood to check for any signs of Down syndromeⁱChromosomal disorder (trisomy 21) characterized by reduced muscle tone, delayed physical and intellectual development. , Patau syndromeⁱCondition marked by genetic duplication of chromosome 13 in an individual, leading to severe neurological and physical defects. , Edward syndromeⁱCondition marked by genetic duplication of chromosome 18 in an individual, leading to severe developmental delays. and other chromosomal abnormalitiesⁱDisorders caused due to anomalies in the number, structure, or composition of chromosomes. (13).

2. Chorionic villus sampling: The doctor will collect a small sample of the chorionic villi tissue from the placentaⁱA temporary organ that develops during pregnancy and provides the fetus with oxygen and nutrients. , and lab-test it for specific fetal disorders. CVS is performed between 10 and 12 weeks in the case of high-risk pregnancies if,

• a woman has a family history of genetic disorders.

• she is above the age of 35 years.

• she or her partner has chromosomal rearrangement (14).

3. Amniocentesis: In this invasive procedure, a needle is inserted into your uterus through the abdomen to extract some amniotic fluid from the amniotic sac. The sample is tested for any chromosomal abnormalities. The test can be carried out as early as between 10 and 12 weeks as early amniocentesisⁱA prenatal test used to evaluate genetic and health abnormalities in the fetus using cells from the amniotic fluid. or will be done after 16 weeks of gestational age (15).
4. NT scan: You may be asked to get an NT scan to rule out chromosomal problems in the fetus, between 11 and 14 weeks of pregnancy.

Note that these tests are not necessary for every pregnant woman but only for those who have a history of chromosomal diseases in their families or in the cases where the doctor suspects something to be wrong.

In other safer cases, it is just the ultrasound and some comprehensive blood tests. Of course, you need to follow it up with some self-TLC.

Things to know

Your provider may advise a blood test to ascertain your immunization status against measles, varicella, mumps, and rubellaⁱA viral infection characterized by red rashes, fever, and sore throat, which may cause severe fetal complications during pregnancy. . The test will also help determine your blood type and Rh factor (24).

10 Tips For A Better 10th Week Pregnancy

The first trimester is the most difficult phase of pregnancy. You may want to follow these tips to ease up the discomforts of the tenth week.

1. Avoid wearing tight clothes. Instead, wear loose shirts and elastic waistband pants. Buy maternity bras.

2. Avoid cleaning your pet’s litter box during this time. It prevents transmission of any parasitic infection through the pets.

3. Do not take any medications without your doctor’s prescription.

4. Follow oral hygiene to prevent gingivitis. Brush your teeth twice every day, and go for regular dental check-ups.
