What's happening with baby
At week 5, your tiny embryo is making incredible strides, even though it's still incredibly small – about the size of an apple seed. This week is a foundational one for development. The neural tube, which will eventually become your baby's brain and spinal cord, is actively forming. This is a crucial step in early development. While you won't hear it yet, your baby's heart has begun to beat, circulating blood within their tiny body. Small limb buds are also starting to emerge, which will eventually grow into arms and legs. It's a time of rapid cellular division and the very beginnings of major organ development. It’s truly amazing what’s happening within you, even at this microscopic stage.
