Pregnancy Calendar Week 5


Your baby’s heart, lungs, brain and spinal cord are developing now. Your body is beginning to change. And your HCG hormone level is high enough for you to use a pregnancy test to confirm that you’re an expecting mother. Congratulations! It’s an exciting time along your journey of motherhood.

Your Body

At 5 weeks pregnant, you’ll begin noticing subtle changes to your body and some common symptoms:

Weight Gain:  While weight gain varies and depends on your pre-pregnancy weight, diet and health, you can expect your weight to fluctuate in the range of -5 to 5 pounds during your first trimester.

Breast Tenderness:  Your breasts are growing now, becoming tender and very sensitive as they get ready to produce milk for your baby. Hormones and increased blood flow are some reasons for the soreness and pain you may have.Try these remedies for relief:

  • Apply ice packs, putting a towel between your breasts and the ice.
  • Restrict caffeine and fatty foods, which may aggravate breast tenderness.
  • Eat foods rich in ALA (alpha-linolenic acid), an essential omega-3 fatty acid, which may help. Nuts, chia seeds, flaxseed oil, red meats and dairy products are all good sources.

Frequent Urination:  You’re probably peeing more now and this is because hormonal changes in your body are causing blood to flow at a faster rate through your kidneys, filling your bladder more often. Your blood volume is also rising, as it will throughout your pregnancy, resulting in extra fluid flowing through your kidneys and in your bladder. And your growing uterus is putting more pressure on your bladder.Here’s what you can do to help:

  • Avoid beverages that have a diuretic effect such as coffee and tea.
  • Cut back on drinking fluids a few hours before bedtime (but keep well-hydrated during the day).
  • Lean forward when you pee to help empty your bladder more completely.
  • Increase in Saliva Production: If you’re experiencing this unpleasant symptom, thought to be caused by hormones, try these tips:
  • Eat small, frequent meals and avoid large amounts of starchy food.
  • Drink plenty of water and take frequent sips.
  • Brush your teeth and use mouthwash many times during the day.
  • Suck on hard candy to make it easier to swallow all that saliva.

Sensitivity to Smells: This common symptom is caused (again!) by your elevated hormones. Try to minimize smells that make you feel sick with these remedies:

  • Switch to unscented products for cleaning and personal care.
  • Cook and eat only foods that have a smell you can tolerate.
  • Leave your windows open whenever possible.
  • Use soothing scents to make you feel better such as ginger, lemon or mint.

Your Baby

In the 5th week of pregnancy, your tiny baby is about the size of an apple seed (1/8 of an inch) and looks like a tadpole. It’s only been one week since your baby attached to the wall of your uterus, but it’s quickly developing in a number of ways:

  • Your baby’s heart is beating.
  • Your baby’s heart has begun to form and it’s already pumping blood. At 5 weeks in your womb, it consists of two small channels called heart tubes. These tubes are busy making your baby’s heartbeat.
  • Your baby’s umbilical cord is forming.
  • Your growing baby is getting nourishment from your umbilical cord, which has replaced the yolk sac. It contains three blood vessels that connect your baby to your blood supply, bringing nutrition and oxygen to your baby while also removing waste.
  • Your baby’s arms and legs are developing.
  • Little arm and leg buds can be seen now! Pretty soon you’ll be feeling those baby kicks inside your belly and your baby’s arms will be waving all around.

Diet and Exercise Tips You Should Follow

Your baby’s healthy development depends on what you’re putting in your body and a good exercise routine will help you battle fatigue and keep your energy levels up.Here are tips to incorporate in week 5:

  • Drink plenty of water.
  • Be sure to drink at least eight 8-oz. glasses of water every day. Water helps with the absorption of essential nutrients into your cells, which ultimately reach the placenta and your baby. It also plays a vital role in dissolving and eliminating waste products from you and your baby.
  • Stay on or start a new exercise regimen.
  • If you’re currently exercising 30-40 minutes per week, keep it going! If you’re not exercising yet, begin a walking program of 20 minutes 3-4 times per week. Be sure to get the green light from your doctor first.

Things You Should Do

  • Take a home pregnancy test to confirm pregnancy.
  • Decide who and when to tell.
  • If you smoke, visit for help quitting.

Words You Should Know

Estrogen:  Any of several steroid hormones produced chiefly by the ovaries. It is responsible for the development of female secondary sex characteristics and growth/maintenance of the female reproductive system.

HCG (Human Chorionic Gonadotropin): A hormone produced during pregnancy with a function of maintaining the uterus wall throughout pregnancy.

Neural Tube:  A tube that begins forming in the first trimester and eventually develops into the baby’s brain, spinal cord and nerves.

Placenta:  A temporary organ that joins the mother and baby to allow for transfer of oxygen and nutrients from the mother to the baby, along with release of waste products from the baby.

Progesterone:  Hormone produced first by the ovaries to prepare the womb for the fertilized egg and later by the placenta to maintain pregnancy.
