Your baby at week 5 of pregnancy

Your baby is indeed growing fast but is still a tiny embryo in the 5th week. It could be as small as a sesame seed, measuring up to 5 mm.

Technically speaking, your baby is a mass of cells or layers known as ectoderm, mesoderm, and the endoderm which will subsequently develop into organs.

One of the most vital organs i.e. the neural tube starts forming from the ectoderm, which looks as if your baby is having a tail (called fetal pole); no worries it would disappear as it grows. The heart also starts developing from the mesoderm. Yes, exciting enough, your baby’s heart starts beating and it can pump blood in this week. The embryo will remain in a yolk sac which provides all the nutrients and produces blood cells until the placenta fully forms.
