Welcome to Week 4
Your baby has implanted into your uterine wall this week, so you are now officially pregnant! However, you may not know that yet, as it’s still too early to get an accurate result on your home pregnancy kit.
Update on Your Body
You are likely to experience some early pregnancy symptoms such as headaches, backaches and breast tenderness. These symptoms are very much like those that appear before your periods and may lead you to believe that a period is on its way. However, a missed period is usually a sign that you are pregnant. Week 4 is about the earliest you can get a positive home pregnancy test.
Update on Your Baby
Your baby is composed of three layers of cells right now. The rapid cell division that began last week has formed three layers – the ectoderm, the mesoderm and the endoderm. The ectoderm will develop into your baby’s nervous system, brain, skin, nails, hair, mammary glands, sweat glands, and the enamel of his or her teeth. The middle layer, or the mesoderm, will develop into the heart, blood vessels, skeleton, urinary tract, genitals, and muscles. The inner layer, or the endoderm, will develop into the lungs, lining of the gastrointestinal tract, pancreas, liver, and thyroid. The placenta that connects your baby to your uterus has begun to take shape too.
Your Baby’s Size
0.05 inches, or the size of a poppy seed.
Tips for an Expectant Mom
If you have had a negative pregnancy test this week, you may want to wait another week before you repeat the test; it is still a little early for some pregnancy tests to identify elevated β-HCG levels.
Eat healthy and wholesome food and make sure to include important nutrients in your diet.
Follow a regular, low-intensity exercise routine after having it approved by your doctor.
Ask rickshaw and taxi drivers to drive carefully over potholes and speed-breakers when travelling by public transport.
Look for a hospital and obstetrician in your locality, so that your doctor is easily accessible to you at all times.
Avoid indulging in activities that may result in a fall, such as jumping onto a bus or train.
Tips for an Expectant Dad
Help your partner choose a good obstetrician.
Voice any fears about the road ahead to your partner and doctor; after all, you will play an equally important role in the road leading up to, and after, your child’s birth.
