About baby this week:
Measuring from the crown of his head to his rump, your baby is now about 4cm long. He has all his parts, from tooth buds to toenails and his fingers and toes have fully separated. Your baby is busy kicking and stretching. His movements are so fluid they look like water ballet. These movements will become more frequent as his body grows and becomes more refined.
Most of your baby’s critical development will tail off in the next couple of weeks. His main task during the next six months will be to grow larger and stronger, until he can survive on his own outside your uterus (womb).
You’re getting close to the end of the first trimester. A dark vertical line of pigmentation, called the linea nigra, may appear on your belly. Perhaps you are starting to find sleeping difficult?
You’ll be experiencing so many new physical sensations now that you’re pregnant, some of them less welcome than others. If you’ve noticed that you’re leaking wee when you sneeze or laugh, try not to worry. This leaking is called stress incontinence and it’s common during pregnancy.
As soon as you become pregnant, hormones cause your pelvic floor tissues and muscles to stretch. This can lead to weakness in the sphincter muscles that control the release of wee from your bladder.
When you laugh, cough, sneeze or run, the pressure inside your tummy and around your bladder increases. This pressure squeezes your bladder. Normally, your pelvic floor muscles help to close off the bottom of your bladder. If these muscles are weak or can’t squeeze fully, they can’t do this job.
