FERTILIZATION       

IMPLANATION : THREE WEEKS PREGNANCY

 HOW BABY IS GROWING

 Your fertilized egg is now a tiny ball of constantly multiply cells called a blastocyst. It implants into the lining of your womb and continues to grow. Some of cells will become your baby, while others will become the placenta or the amniotic sac.

 The cells that are developing into a placenta have started to produce the pregnancy hormone hCG(human chorionic gonadotropin). This hormone tells your ovaries to boost production of oestriogen and progesterone which stop your womb from shedding its lining. hCG is also the hormone that will turn your pregnancy test positive 

 meanwhile, amniotic fluid is beginning to form in the cavity that will become the amniotic sac. This fluid will cushion your baby in the weeks and months ahead.
