4 Weeks Pregnant
Your little seed
Right now, your bundle of joy measures about 2mm - it's the size of a poppy seed!
Your little seed has made itself at home, by snuggling up in the lining of your womb. As a result, you may experience some very light bleeding, or period-like cramping. This is relatively common, however it is important to consult your doctor or midwife on any bleeding throughout your pregnancy.
Currently, your baby is being nourished by a yolk sac. In the next few weeks the placenta will form from the amniotic sac around your baby, and this will take over.
36 weeks to go!
