(BC) The 4th Week – Your Little Poppy Seed

(BC) The 4th Week – Your Little Poppy Seed

Your baby now is practically microscopic. Their size can be as big as the size of a poppy seed but no more. It’s called the blastocyst and currently, it has completed its long and arduous journey from the fallopian tube into the heart of your uterus. Occasionally, you would have slight bleeding (spotting) but that just means your baby is trying hard enough to get through you to live. He is a fighter. Better make a super strong connection now that would be at least unbreakable for the next 8 months or so.

Instead of just being a clump of cells, your embryo now has three distinct layers. The outermost layer (ectoderm) would form the nervous system, outer layer of skin, hair and eyes. By this moment, your baby’s neural tube which is the building block for the formation of brain, spine and backbone has already been formed. It seems healthy but  I hope you are still taking your folic acid frequently though. I mean, it’s easy, right? Don’t chug the whole bottle though.

The second layer or the middle is the mesoderm. Soon, this layer would develop into a variety of important organs that your baby can’t live without. Sex organs, bones, heart, muscles and kidneys; all of these came from the mesoderm of your embryo. Better hope it would develop properly then. How about the inner layer? It’s called the endoderm. This particular layer would form your baby’s liver, digestive system and sure, the lungs. It’s vital for them right after their birth. Yeah, not now. Soon.

If you are eager to do an ultrasound scan, just so you know, the thing that you can see on that machine up to this point, is just a tiny dot which we called the gestational sac. However, it’s unlikely for you to have the first ultrasound scan as early as the first month. Usually, when you call your doctor to set up an appointment for prenatal screening, they would see you in a month time. So the earliest scan you would have could be done as early as 6 to 8 weeks of gestation.

There is no need to see a doctor early if you are healthy as a horse. Just remember to eat well, avoid drinking alcohol and smoking, enjoy your bits of freedom and stay hydrated. It’s certainly a big day for you but you better get some rest. We will see you next month.
