It is when the fertilised egg implants itself in the lining of the uterus
Because if the egg is fertilised, it implants into the thick uterus lining. If it wasn't thick, there would be nothing for it to implant into. Also, once the egg is fertilised and is implanted there, it provides protection around the egg
No, you can't menstruate while pregnant. Menstruation only occurs when the egg released during ovulation isn't fertilised, if it is fertilised then the egg will implant in the uterus lining - if the uterus lining were to shed it would cause miscarriage.
the uterus lining thickens ready for the egg to be fertilised . if the egg is not fertilised then it will pass through the vagina as blood (period).
If you are referring to menstruation, they do not bleed from their 'butts'. The blood is the thickened lining of the uterus detaching and falling out. This happens once every month if the woman does not become pregnant as the Uterus lining grows to give a resting place for a fertilised egg to become a foetus and then a baby. If the egg is not fertilised by sperm following sex, the lining of the Uterus is not needed and is rejected by the body.

Every month, the uterus prepares for the possibility of pregnancy, so if nothing happens, the uterus sheds the lining and passes out of the body.
The uterus lining will come loose and a mentral cycle will begin.
The blood lining of the uterus gradually thickens during a woman's menstrual cycle in order to be prepared to receive the fertilized egg. This lining will shed during the menstrual period if no fertilized egg has implanted.
The uterus produces a lining called the endometrium. The endometrium creates an environment for the fertilized egg to implant to and grow. the lining is thick so when the fertilised egg lands on it, it can have like a sort of perfect house to live in
Conception is the point at which the sperm and egg meet also known as fertilisation. Implantation is when the fertilised egg reaches the uterus and implants into the lining of the uterus.
