Your baby this week
- The neck is more defined, letting the head lift off the chest
- Fine, downy hair called lanugo begins covering the skin
- The liver and spleen are actively producing red blood cells
- Genitals have developed enough that sex can sometimes be seen on ultrasound, though many wait for a later scan to confirm
Your body this week
- A visible bump often starts becoming noticeable to others around now
- Skin changes like a faint dark line down the belly (linea nigra) can appear
This week's tip: Loose, comfortable clothing and supportive bras can help as your body starts changing shape more noticeably.
