Welcome to week 4 of your pregnancy! This week, your baby is as big as a poppy seed. Here’s what else you can expect this week.
Your baby
Your baby is the size of a poppy seed, just a little bigger than this full stop. The fertilised egg (or eggs) — known as a zygote — has arrived in your womb and implanted into its wall. It has divided into two; one group of cells will become the embryo, the other its life support mechanism, the placenta.
The placental cells immediately begin to produce Human Chorionic Gonadotrophin (hGC) the hormone that a pregnancy test looks for before it shows you those life-changing blue lines.
You
Early pregnancy symptoms including sore boobs, feeling bloated, and moodiness. If you’re not expecting to be pregnant you can easily mistake them for PMS – particularly if you experience implantation bleeding and mild cramping.
Your heart rate is already increasing. Notice a strange taste in your mouth? It’s another early sign. At this point, the levels of hCG might not be sufficient to show a positive pregnancy test result, which is something to note.
Tip: It’s still early days in the life of your little poppy seed and while it may not feel like much is happening yet, there’s a lot going on behind the scenes.
Reading up on all the weird and wonderful things that are happening to you is a lovely way to relax in the early months of pregnancy. Check out our ‘Top 10 Books To Read When Pregnant’.
