Your Pregnancy

Don't get caught up in worrying about being pregnant before you are sure. A missed period is the most common indication, but it doesn't necessarily mean you are pregnant.

Signs You Might Be Pregnant:

•Late period
•Tender or swollen breasts
•Frequent urination
•Nausea or vomiting
•Lightheadedness or fainting
•Food cravings or aversions
•Darkening of the nipples


If you believe you might be pregnant and want to know for sure, the best way to do this is to visit your doctor. If you are not ready to take that step, the Crisis Pregnancy Centre offers free self-administered pregnancy tests, as well as emotional support as you absorb the results of the test. For more information please contact us.

If you know for sure that you are pregnant here is some valuable information about your baby.


Understanding your pregnancy

First trimester week 1-12

at 4 weeks

at 8 weeks

At the end of 8 weeks, your baby is a fetus and looks more like a human. Your baby is nearly 1 inch long and weighs less than 1/8 of an ounce.

  • Your baby's brain and spinal cord have begun to form.

  • The heart begins to form.

  • Arm and leg buds appear.

  • Your baby is now an embryo and one-twenty-fifth inch long.

• All major organs and external body structures have begun to form.

• Your baby's heart beats with a regular rhythm.

• The arms and legs grow longer, and fingers and toes have begun to form.

• The sex organs begin to form.

• The eyes have moved forward on the face and eyelids have formed.

• The umbilical cord is clearly visible.

at 12 weeks

Now, at about 3   inches long, your baby weighs almost an ounce.

• Muscle tissue and bone continue to form, creating a more complete skeleton.

• Skin begins to form. You can nearly see through it.

• Necib (mih-KOH-nee-uhm) develops in your baby's intestinal tract. This will be
  your baby's first bowel movement.

• Your baby makes sucking motions with the mouth (sucking reflex).

• Your baby reaches a length of about 4 to 5 inches and weighs almost 3 ounces.


Second trimester week 13-28

at 16 weeks

• The nerves and muscles begin to work together. Your baby can make a fist.

• The external sex organs show if your baby is a boy or girl. A woman  

  who has an ultrasound in the second trimester or later might be able to find 

  out the baby's sex.

• Eyelids close to protect the developing eyes. They will not open again until
  the 28th week.


at 20 weeks

Now halfway through your pregnancy, your baby is about 6 inches long and weighs about 9 ounces.

at 24 weeks

If your baby is a boy, his testicles begin to move from the abdomen into the scrotum. If your baby is a girl, her uterus and ovaries are in place, and a lifetime supply of eggs have formed in the ovaries. Now at about 12 inches long, your baby weighs about 1½ pounds.

Third trimester week 29-40

at 32 weeks

Your baby is gaining weight quickly, about one-half pound a week. Now, your baby is about 15 to 17 inches long and weighs about 4 to 4½ pounds

at 36 weeks

at 37 - 40 weeks

At birth, your baby may weigh somewhere between 6 pounds 2 ounces and 9 pounds 2 ounces and be 19 to 21 inches long. Most full-term babies fall within these ranges but healthy babies come in many different sizes.

• Your baby is more active. You might feel slight fluttering.

• Your baby is covered by fine, downy hair called lanugo (luh-NOO-goh) and a waxy
   coating called vernix. This protects the forming skin underneath.

• Eyebrows, eyelashes, fingernails, and toenails have formed. Your baby can even
  scratch herself.

• Your baby can hear and swallow.



• Bone marrow begins to make blood cells.

• Taste buds form on your baby's tongue.

• Footprints and fingerprints have formed.

• Real hair begins to grow on your baby's head.

• The lungs are formed, but do not work.

• The hand and startle reflexes develop.

• Your baby sleeps and wakes regularly.



• Your baby's bones are fully formed, but still soft.

• Your baby's kicks and jabs are forceful.

• The eyes can open and close and sense changes in light.

• Lungs are not fully formed, but practice "breathing" movements occur.

• Your baby's body begins to store vital minerals, such as iron and calcium.



 The protective waxy coating called vernix gets thicker.

• Body fat increases. Your baby is getting bigger and bigger and has less space to
   move around. Movements are less forceful, but you will feel stretches and wiggles.

• Your baby is about 16 to 19 inches long and weighs about 6 to 6½ pounds.



  • By the end of 37 weeks, your baby is considered full term. Your baby's organs are ready to function on their own.


  • As you near your due date, your baby may turn into a head-down position for birth. Most babies "present" head down.
