At 3 weeks pregnant, pregnancy has just started. The man’s sperm meets the woman’s egg, and they join together. This is called fertilization. After this, the fertilized egg slowly travels to the uterus (womb). You may not feel anything yet, but this is the start of a new life.
Inside the body, the egg starts dividing into many small cells. It will soon stick to the wall of the uterus. A pregnancy hormone called hCG also starts forming, but it is too early to show in a home pregnancy test.
Some women may feel light cramps or see small spotting (bleeding), while many don’t feel anything at all. From now on, it’s important to stay healthy. Start taking folic acid tablets and avoid smoking or alcohol. These first days are very important for your baby’s growth.
