Week 4: How Big is Your Baby?

This is the week that marks the beginning of your baby’s embryonic period even if your baby is still microscopic. It’s around 1mm and weighs around 0.1g, the size of a poppy seed.

Your Baby’s Development
  • The amniotic sac is now present at pregnancy week 4. This will be home to your baby until the time of birth. Also present is the yolk sac which will produce your baby’s red blood cells. The yolk sac is also responsible for delivering all nutrients to him/her until the placenta is developed and ready to take over this function.
  • This is the beginning of a major activity for him/her. From now onwards, for the next six weeks, all of his/her organs will begin to develop (and some of them will even begin functioning!)

 

Pregnancy Symptoms
  • You will probably be taking a home pregnancy test to confirm your suspicions of being pregnant—not all women find out about their pregnancy this early on. Just remember that for the most accurate results you must wait for at least a week after your expected period.
  • You may not yet be feeling much different yet, but brace yourself for morning sickness in the very near future.
  • You may experience some bloating, due to the increased levels of progesterone, the pregnancy hormone.
  • There might be some mild cramps and perhaps a bit of bleeding, this is because your baby travels up the fallopian tube and implants him/herself to the wall of your uterus.
  • Your fluctuating hormones could be causing mood swings.
Pregnancy Care
  • Once you confirm your pregnancy you need to stop smoking and absolutely limit the intake of alcohol and caffeine.
  • Avoid unpasteurised soft cheeses such as camembert and brie, as well as undercooked meats and soft-boiled eggs to avoid e-coli and salmonella infections.
  • Avoid fish with high mercury levels such as shark, swordfish and king mackerel.
