How Many Months Are 15 Weeks Pregnant?

At 15 weeks of gestational age, you are three-and-a-half-months pregnant. You are in the second trimester by this week and may start to feel less nauseated in the mornings.

Keep reading to learn what is going on with your baby, the symptoms to expect, and how to take care of yourself this week.

How Big Is Your Baby At 15 Weeks?

At 15 weeks, the baby is as big as an apple (1). They measure 3.98in (10.1cm) in length and weigh 2.47oz (70g) (2).

Next, we tell you about fetal anatomy and how the baby’s organs are growing.

The Baby’s Development This Week

In the 15th week, your baby’s organs are changing as follows.

Body partsDevelopment

The baby’s bone begins to ossify at around 15 weeks pregnant. This means the baby’s skeleton may be seen if an x-ray is taken (16).

What Symptoms Of Pregnancy Do You Experience In The 15th Week?

The physiological changes you experience now include:

  1. Weight gain: the weight gain should be as per the BMI (7).
BMIBelow 18.518.5 – 24.925 – 29.930 and above
Weight gain28-40 pounds25-35 pounds15-25 pounds11-20 pounds
  1. Faintness or dizziness: The growing uterus puts more pressure on the blood vessels, reducing the blood flow to the brain and causing fatigue or lightheadedness. Sometimes staying hungry for a long time can also cause lightheadedness.
  1. Round ligament pain: The pain is either felt on one side of the abdomen or both sides, due to the stretching of the groin ligaments.
  1. Insomnia: Backaches, hip pain, and leg cramps make sleeping difficult. Using a pillow around the stomach and between the legs can offer some relief.
  1. Frequent urination: The uterus’ pressure on the bladder increases the frequency of urination.
  1. Constipation: The progesterone hormone relaxes the muscles of the digestive tract, causing the food to remain in the tract for longer than usual and resulting in constipation.

Joolia Gulia, a mom of four, shares on her blog, “All sorts of strange musical noises emerge from my gut and they sound like any of the following: screeching, popping, barking, clicking, and my personal favorite…..the Dumb and Dumber gurgle. Not only am I full of enough gas to implode a small house but I’m also constipated (i).”

  1. Swollen gums: The ligaments in the mouth are affected by the changes in the hormones. Pregnancy tumors or swelling between the teeth may appear due to plaque. If morning sickness is persistent, then an increase in mouth acids can cause tooth decay (8).
  1. Shortness of breath: The hormone fluctuations cause more blood flow to the mucous membranes that make them swell and soften, causing stuffy nose and congestion. It also causes breathlessness. Try not to blow it hard as it can lead to nosebleeds.
  1. Heartburn and indigestion: As the digestive tract relaxes, the stomach acids are pushed towards the esophagus, resulting in heartburn and indigestion.

Genevieve Howland, a childbirth educator and a mother of three, tells how she dealt with acid reflux during pregnancy. She says, “I have been consuming my digestive enzymes and a glass of milk with each meal which really helps (ii).”

The stomach acids may cause heartburn.

  1.  Occasional headaches: Hormonal fluctuations or stress can lead to headaches. Meditation or yoga can help relieve stress.
  1. Varicose veins: The extra blood volume puts pressure on the blood vessels causing the veins in the legs to swell.
  1. Excessive salivation: Hormonal changes also cause excessive salivation. Also, the body produces excess saliva to neutralize the gastric acid produced due to gastroesophageal reflux.
  1. Your body starts to change externally, while your emotional state is also vulnerable.

If a prenatal care appointment is scheduled with the doctor this week, the following tests will be done:

  • Weight check
  • Blood pressure
  • Second-trimester screening (10): Ultrasound, several blood tests including the maternal serum screening test (MSS), a blood test similar to the one done during the first trimester, are scheduled at this time. These tests are referred to as ‘multiple markers’ or ‘quad screen’ tests.

They are done to determine the level of four substances namely AFP, estriol, inhibin, and human chorionic gonadotropin in the blood to evaluate the risk of:

  • Down syndrome
  • Trisomy 18
  • Neural-tube defects (NTDs) such as spina bifida in the fetus.
  • Defects in the abdominal wall of the fetus

While this screening test is not 100% accurate, it can help determine the chances of having chromosomal abnormalities and refer to the next diagnosis.

  • Amniocentesis (11): It is a diagnostic test carried at 15 to 20 weeks of pregnancy. This test is done if the results of the screening test are not normal. A small amount of the amniotic fluid taken from the womb is tested to check for any genetic abnormalities (like cystic fibrosis, sickle cell disease, and heart defects) and congenital disabilities (like neural tube defect or spina bifida).

Some tests may not be safe for you, so talk to your doctor before getting any diagnostic procedures done.

The doctor may measure your fundal height at 15 weeks. A higher fundal height may indicate a breech position, while a smaller fundal height may indicate a sideways position (16).

When the going is good, you can make it better by following some tips.

Tips To Follow

Here are a few tips you can follow for a healthy pregnancy:

  • Eat smaller meals at regular intervals.
  • Follow a healthy diet that includes meat, cereals, pulses, dairy products, fresh fruits, and vegetables. The right amount of calorie intake during the second trimester is 2,200 calories per day (12).

  • Avoid consumption of caffeine and alcohol as it can affect the baby’s development.
  • Rest properly and try to sleep on your left side.
  • In the case of nausea, drink lemonade, eat watermelon or sniff a lemon.
  • Avoid skipping meals or lying down immediately after having meals.

  • Take prenatal vitamins and supplements (folic acid, vitamin B6) along with iron and calcium daily.

  • Avoid wearing heels and switch to flats and slippers.
  • At this point in time, the fetal hearing sense will begin to develop Communicate with your baby and they will likely perceive the sound of your voice.
