"Period" is a term for menstruation ... the biological cleaning out of the endometium (inner lining) of the uterus - done to prepare the uterus to receive the fertilized egg.
The fertilized egg "implants" (sticks to) the wall of the uterus and develops into a fetus (complete with placenta) which will eventually be born as a child.
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).
your uterus lining is breaking down because no embryo (fertilised egg) has needed it. it comes out the body as blood.
Thickening of the womb happens every month during a woman's monthly cycle. It is when the lining of the womb builds up so that if the egg is fertilised it will have a soft, spongy lining to implant into and will be protected throughout the pregnancy If the egg is not fertilised, the lining breaks down as it is not needed, and that is what a period is The thickening of the womb is caused by hormones that trigger it to thicken
Periods are the shedding of the uterine lineing when an egg is not fertilised.
The elephant is a mammal, and gives live birth after a period of gestation. The only egg is released by the female and is fertilised by the sperm from a male, all of which happens internally in the female.

Menopause means a stopping of having periods. There IS no period blood.
Menstruation is caused by the break-down of the lining of the womb. This happens when no egg implants. Once an eggs is fertilised it attaches to the womb's lining, so the lining does not break down.

You're having your period. It is completely normal, and a sign that you are mature.
If your ovum is not fertilised by a sperm, it will pass through the fallopian tube and disintegrate in the womb after 12-48 hours. Around 10 days later, the lining of the womb sloughs off and you have your period.
