Pregnancy Week 5
The central nervous system (the brain and spinal cord), muscle and bone formation are beginning to take shape in your baby. During this time, your baby's skeleton is also starting to form.
Your period is late and if you haven't already taken a home pregnancy test, taking one now should confirm your pregnancy. It?s still too early for you to start "showing", since there hasn't been any big changes in the size of your abdomen. More below.
You may start noticing some early symptoms of pregnancy during this week. Morning sickness (which can really occur at any time of the day or night), nausea and vomiting, frequent urination, breast changes- such as tenderness, tingling in the breasts or nipples- are all early signs. Fatigue or tiring easily is also common at this time.
By the end of this week of pregnancy, the earliest blood elements and vessels have formed in your baby and developing placenta. Circulation now begins and the heart is developing rapidly. The circulatory system becomes the first functioning organ system.
