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.
The uterus lining changes in thickness during the menstrual cycle in response to hormonal levels. In the first half of the cycle, estrogen causes the lining to thicken in preparation for a potential pregnancy. If fertilization does not occur, estrogen levels drop and the lining sheds during menstruation.

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
The process is called menstruation.The uterus lining sheds when the egg wasn't fertilized and has to be deposited through the vagina.The purpose/function of the uterus is to protect the period of fertilisation of the ovum.Uterus lining sheds only when egg is not fertilized.Uterus lining remains thickened when the egg is fertilised(woman is pregnant).The process by which the uterus sheds its lining is known as menstruation. Menstruation occurs in females from the onset of puberty until the menopause.
Each month, from the age of about 12, a woman releases one egg each month. If this egg is fertilised by sperm during sex, a baby is made. If it isn't fertilised, it starts to break down and the body needs to get rid of it. Also, during the month, the lining of the woman's uterus/womb starts to build up and thicken so that if the egg is fertilised it will be able to implant into the lining and grow. If the egg is not fertilised, the body also needs to get rid of this built-up lining. So, once the egg has been released, and not fertilised it will start to break down and the remains leave the uterus through the cervix and out of the vagina. As the lining of the uterus starts to break down and detach, blood vessels are ruptured and this is where the blood comes from.
your uterus lining is breaking down because no embryo (fertilised egg) has needed it. it comes out the body as blood.
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.
