Pregnancy Weekly Guide for Moms [15 Weeks Pregnant]

Pregnancy Weekly Guide for Moms [15 Weeks Pregnant]

Hooray! You’re in your 15th week, mama! At this phase, you’re entering the second trimester, which brings a wave of exciting changes for you and your growing baby.

I remember embracing the exciting changes and mounting excitement of parenting during my 15th week of pregnancy (and I know you will too!)

From the blossoming baby bump to new sensations and milestones, this guide will provide helpful information about what to expect during this crucial stage.

Join me, as I recount my experiences and share essential information for moms-to-be at 15 weeks pregnant!

Baby’s Development at 15 Weeks

Baby’s Development at 15 Week

Every passing week will bring new, awe-inspiring, visible, and hidden developments within the tiny being growing inside you. 

From the formation of their delicate features to the maturation of essential organs, your baby’s development at 15 weeks is a testament to the miracle of life.

In this section, I will take you through the milestones that are unfolding during this stage, offering insights into the fascinating world of your baby’s growth and transformation.

GOOD TO KNOW: At 14 weeks pregnant, your uterus has grown enough to show a small baby bump.

How Is Baby Like?

At 15 weeks, your baby is rapidly growing and developing. Their body is becoming more proportional, with their head measuring less than half their body size. 

Your baby’s limbs also develop, allowing them to move MORE FLUIDLY. Your baby’s facial attributes are evolving, and they’ll begin to look more like a newborn. 

Their eyes, although still fused shut, are moving closer together. The ears are shifting to their correct position on the sides of the head, and their tiny nose and lips are becoming more defined.

Your baby is becoming more active. Although you may not feel consistent or strong movements, your baby can now kick, stretch, and move their limbs.

They can also make slight facial expressions, like winking or frowning.

Baby Is As Big As a Pear

At 15 weeks, your baby is approximately the size of a pear. They measure at about 4 inches from crown to rump. 

That may seem small, but that’s because your baby’s legs are still curled towards their torso. The baby’s average weight at this phase is about 2.5 ounces.

Your baby’s skin is still very thin and translucent, and blood vessels are visible. Their skin is also covered with a fine hair called lanugo, which helps regulate body temperature. 

Their skin will also be covered in a waxy substance called vernix caseosa to protect it from the amniotic fluid.

They can move their arms and legs, and their joints start to form, allowing greater flexibility and movement.

GOOD TO KNOW: At 16 weeks pregnant, your baby will be roughly the size of an avocado, and their movements will become more coordinated.

Baby’s Features Are More Prominent

By the 15th week, your baby’s features become more profound as their development progresses. Your baby’s facial features are becoming more distinct. 

The neck is getting longer and stronger, allowing your baby to move their head more freely. Additionally, the nails on their fingers and toes start to form.

Their digestive system is also MATURING. Your baby’s stomach produces digestive juices, and their intestines are developing the ability to absorb nutrients. 

The intestines, which have been developing inside the umbilical cord, are beginning to move into the baby’s belly.

Your baby’s sense of touch is also improving, and they may be able to feel gentle pressure or touches against the womb.

Getting Ready for the Outside World

At 15 weeks, your baby’s development is getting ready for the outside world.   

Your baby’s muscles are continuing to DEVELOP and STRENGTHEN, enabling them to move a bit more. Their skeleton is also becoming more solidified as their bones continue to ossify. 

The nervous system is maturing, and your baby’s brain is rapidly developing. The nerve cells in their brain are forming bonds and pathways that will allow for more complex functions.

Your baby may begin swallowing amniotic fluid, but you don’t need to worry. This helps their gut practice and it’s a good preparation for digesting breast milk or formula after birth.

If your baby is a girl, her ovaries will continue maturing. If your baby is a boy, his testes will begin pushing down from his abdomen to the scrotum.

Mommy at 15 Weeks of Pregnancy

The 15th week is marked by notable changes in the mother’s body, feelings, and general well-being as she enters the second trimester. 

As the baby develops, the mother’s experience becomes a remarkable blend of physical transformation, heightened senses, and a connection to the life growing within her. 

Let’s examine what to expect and the essential aspects of a mommy’s journey at 15 weeks of pregnancy.

No More Early Pregnancy Symptoms

By now, pregnant mamas will find RELIEF from the early pregnancy symptoms they may have experienced in the first trimester. 

Morning sickness and feelings of nausea often begin to subside or disappear completely for most women. 

The intense fatigue accompanying early pregnancy may also lessen, allowing mommy to regain some of her energy. Many women notice a significant increase in their energy levels. 

NOTE: Leukocytes in urine during pregnancy can indicate a urinary tract infection (UTI). It’s important to consult your doctor for proper diagnosis and treatment.

Bleeding Gums

Around the 15th week of their pregnancy, some moms may encounter bleeding gums. This condition is known as pregnancy gingivitis, and can affect them throughout their prenatal journey. 

Your pregnancy can cause high hormone levels, notably progesterone, which can cause abnormalities in the gums. It can make the gums more SENSITIVE and prone to inflammation. 

Pregnancy also increases blood flow throughout the body, including the gums. 

This improved circulation can cause the gums to become more engorged, sensitive, and susceptible to bleeding.

Pregnancy gingivitis is marked by symptoms like swollen, tender, or reddened gums and bleeding while brushing or flossing.

GOOD TO KNOW: Fluctuating hormones during pregnancy can contribute to body odor changes, a common occurrence for many expectant mothers.

Visible Weight Gain

Weight gain is a normal part of pregnancy as the mommy’s body undergoes various changes to support the growing baby. It indicates the baby is developing and that your body is adapting accordingly.

The recommended weight gain during pregnancy differs depending on pre-pregnancy weight, general health, and whether you have multiple pregnancies (e.g., twins). 

On average, by 15 weeks, moms-to-be may have gained around 5-10 pounds, or slightly more if they’re carrying two or more kids.

Weight gain is NOT LIMITED to the baby’s growth. It also includes the weight of the placenta, amniotic fluid, increased blood volume, bigger breasts, and uterine enlargement.

EXPERT TIP: Using a pregnancy stretch mark cream can help moisturize and nourish your skin, reducing the appearance of stretch marks during pregnancy.

Pregnancy Symptoms at 15 Weeks

Pregnancy Symptoms at 15 Weeks

Here are some pregnancy symptoms that may manifest during this phase:

  • Decreased Nausea and Morning Sickness: By 15 weeks, morning sickness and feelings of nausea often subside for many expectant mothers.
  • Increased Energy Levels: As the fatigue of the first trimester diminishes, many women notice a boost in their energy levels.
  • Breast Changes: You may experience breast-related changes, such as increased sensitivity, enlargement, and darkening of the nipples and areolas.
  • Mood Swings: Hormonal fluctuations during pregnancy can lead to mood swings and emotional changes.
  • Frequent Urination: The growing uterus puts pressure on the bladder, leading to more frequent urination.
  • Round Ligament Pain: Women may experience occasional sharp or dull pain on one or both sides of the lower abdomen as the uterus expands.
  • Skin Changes: Some women may experience skin darkening, such as a dark line (linea nigra) running vertically down the abdomen or darkened patches on the face (melasma or “mask of pregnancy”).
  • Nasal Congestion and Bleeding Gums: Increased blood flow and hormonal changes can lead to nasal congestion and occasional nosebleeds.
  • Backache: As the pregnancy progresses, the growing uterus shifts the center of gravity and may cause strain on the back, leading to back aches and discomfort. 
  • Shifts in Libido: While some may detect a boost in libido, others may undergo a decline. These changes are normal and can vary from woman to woman.

QUICK TIP: Compression socks for pregnancy are great because they can enhance blood circulation and reduce swelling in the legs and feet, which is a common issue during pregnancy.

Tips for a 15-Week Pregnant Mom

Tips for a 15-Week Pregnant Mom

Here are some tips for the 15th week of your pregnancy:

  • Sustain a Healthy Pregnancy Diet: Concentrate on consuming a well-balanced diet rich in nutrients to help your baby’s growth and development. Include various fruits, veggies, whole grains, lean proteins, and dairy products. Take in lots of fluids throughout the day to remain hydrated. You can also consume pregnancy-safe protein powder to meet your increased protein needs during this crucial time.
  • Continue Taking Prenatal Vitamins: Take your prenatal vitamins as directed by your doctor to ensure you get vital nutrients like folic acid, iron, and calcium for the growth of your unborn child.
  • Stay Active: Engage in regular, moderate exercise with your healthcare provider’s approval. Activities like walking, swimming, prenatal yoga, or low-impact aerobics can help you stay fit, improve circulation, and alleviate discomfort.
  • Practice Good Posture: Pay attention to your posture to alleviate back aches and muscle strain as your baby bump grows. Maintain an upright posture while sitting and standing, and consider using supportive pillows when resting or sleeping.
  • Get Adequate Rest: Pregnancy is physically demanding, so prioritize getting enough rest and sleep. Find a comfortable sleeping position that supports your growing belly.
  • Manage Stress: Pregnancy can bring about various stressful emotions. Discover healthy ways to manage stress, such as relaxation techniques, deep breathing exercises, or a prenatal massage.
  • Maintain Good Oral Health: Brush your teeth at least twice daily and floss regularly to keep your gums and teeth healthy. If you experience bleeding gums, consult your dentist for guidance and proper oral care during pregnancy.
  • Pick Up Maternity Clothing: Consider investing in comfortable and supportive maternity clothing as your body changes. Opt for clothing that accommodates your growing belly and supports your back and breasts.
  • Attend Prenatal Appointments: Keep up with your prenatal appointments to monitor your baby’s growth, address concerns, and receive any necessary prenatal tests.
  • Connect with Other Expectant Mothers: Joining prenatal classes or support groups can give you a sense of community and help you connect with other moms-to-be who may be going through similar experiences.

CLOTHING TIP: Maternity leggings are a comfortable and versatile wardrobe staple for expectant mothers, providing support and flexibility throughout pregnancy.


This section addresses common questions and concerns that expectant mothers may have during the 15th week of pregnancy. 

How Do I Know My Baby Is Okay at 15 Weeks?

At 15 weeks of pregnancy, it is understandable to be worried about your baby’s well-being. You may start feeling gentle flutters or movements from your baby, known as quickening. 

Feeling regular movements is a positive indication that your baby is active and developing as expected.

Steady growth and appropriate weight gain are also signs that your baby is developing well.

Is It Normal to Feel Pressure in the Lower Abdomen at 15 Weeks?

It’s common to feel pressure in the lower abdomen at 15 weeks of pregnancy. 

As your infant develops and your uterus expands, it puts pressure on the surrounding organs and ligaments, leading to feelings of pressure and discomfort in the lower abdomen. 

As your uterus extends to accommodate your growing baby, it gradually moves higher in your abdominal cavity. This upward movement can contribute to your sensations.


The 15th week of pregnancy brings significant developments and changes for the baby and pregnant mother. 

As their early pregnancy symptoms subside, moms-to-be can look forward to increased energy levels and a MORE STABLE emotional state. 

By staying educated and caring for yourself, you can confidently go through this journey as you move into the second trimester. 

Remember, every pregnancy is different, and your physician is your best resource for personalized guidance and support. 
So mama, enjoy this remarkable phase of your pregnancy as you continue to prepare for the arrival of your little one.
