You are now 11 weeks pregnant (63 days since conception) and at the start of week 12.

Your baby measures about 5 cm (2 inches) from crown to rump and weighs about 8 grams (0.28 ounces), nearly doubling in size during the last week!

 

Your baby now has a limited ability to suck and swallow, although this action is not fully mature until 24 to 28 weeks. Their taste buds have developed to taste the amniotic fluid that surrounds them and their kidneys are now functioning and secreting fluid into their bladder. Your baby will soon pass a type of clean urine into the amniotic fluid, in a continuous cycle of swallowing and urinating this fluid to keep their kidneys functioning until birth.

Your baby also breathes amniotic fluid into their lungs to strengthen the muscle under them (called the diaphragm) and to regularly practise rhythmic expansion of their lungs. Their stomach now produces gastric juices and they have about 20 baby teeth in their gums!

Your baby's sex organs are still developing although their typical male or female characteristics are not yet obvious. Under the influence of increased testosterone for boys (or the lack of testosterone for girls), your baby's genitals start taking their individual shape to look distinctly male or female by 15 weeks.

Your baby's movements are now more coordinated and purposeful and a few women can sense their baby moving as early as 12 weeks (although this is not common). Regular movement is now important for your baby's growth and development. Without it their muscles would waste, their joints would seize and their bones would become brittle. Movement of some description is now a daily part of your unborn baby's life (when they are awake!)

 

Physical changes 

 

Uterus growing

 

By the end of this week your uterus will start to grow up out of your pelvic bones and your caregiver (and you) may be able to feel the top of the uterus, called the fundus. If this is not your first pregnancy, or you are carrying twins (or more), you may be able to feel the top of the uterus earlier (possibly after 10 or 11 weeks).

Body temperature

 

You may notice an increase in your body temperature. This is due to your body's metabolism increasing by 20%, creating more heat and slightly raising your temperature. Increased blood flow also makes your skin warmer and you may sweat more. In the summer months, dressing in layers can help with temperature changes. Take care not to overheat when exercising.

 

Emotional reactions 

 

A few women find their emotions are still fragile and they continue to experience moments of unpredictable tears or perhaps feel a new sense of vulnerability. This may stem from feelings about yourself, or about your relationship (if you have a partner) and can manifest in wanting your partner close by, or making efforts to nurture your relationships with others. Communicating remains important as you continue to adjust.

 

It is common to wonder whether your baby is growing normally or to consider what you would do if something were wrong. These feelings may be instinctive or possibly related to unexplainable thoughts like "Do I deserve a healthy baby?" For some parents there may be concrete reasons such as disorders that run in the family.

 

Fears are often triggered by caregivers offering screening tests for abnormalities, which may be something you want or find confronting, challenging your feelings about your body's ability to produce a healthy baby. Unfortunately, no amount of tests can give you an iron-clad guarantee, but thankfully most babies are born well and healthy.

 

Other considerations

 

What to expect at your first pregnancy visit

 

Your first visit may be something you look forward to with excitement and eager expectations, or perhaps you anticipate it with a degree of nervousness and perhaps apprehension. If you have never been pregnant before, it can be difficult to know what may be involved. Generally your first visit is timed to happen around 10 to 14 weeks.
