The common site of the implantation in the uterus is A. The upper uterine portion. The uterus is the area where the implantation of the fertilized egg usually takes place but there are moments when the egg implants itself somewhere in the abdominal cavity. This can be dangerous to the mother because this area is not fit for carrying a child.
A lot of fertilized eggs that are implanted in the abdominal cavity usually die or they may grow to an ectopic pregnancy. There are times when having an ectopic pregnancy may not be evident in the beginning but as time goes by, the woman would start experiencing severe abdominal pain. There are also some pregnant women who report that they can feel the parts of the fetus immediately. Women are recommended to visit with their medical doctors to diagnose this condition.
