when the ovary drops into the womb blood starts to collect inside the womb, if a spurm is not in the womb from a man then it all gets pushed out the vagina and that is a period. however if there is a spurm, the spurm and ovary get stuck together and stick to the blood in the womb, then it starts developing into more and more cells this turns into a baby. you get identical twins if the ovary splits in half then you need two spurm (one for each half) to create two babies, they are identical because they are out of the same ovary, you get non identical twins if two eggs drop at the same time. this only happens once a month and only in women...

Estrogen
Human females have menstrual cycles so that they can get pregnant, and thus continue the human race! During the menstrual cycle a woman will ovulate and the uterus will prepare itself for the possibility of pregnancy, if pregnancy doesn't occur the uterus lining sheds and the process starts again.
Anigogenesis refers to the development of mature, or Graafian, follicles in the ovaries. The two events in a woman's life that depend on anigogenesis are ovulation, when a mature egg is released from the ovary, and the formation of the corpus luteum, which produces progesterone to help prepare the uterus for a possible pregnancy.
ovaries
The ovaries do not actually produce a female gamete each moth. The ovaries prepare a female gamete for fertilization every month.
Progesterone is secreted by the corpus luteum of the ovary and by the placenta, that acts to prepare the uterus for implantation of the fertilized ovum, to maintain pregnancy, and to promote development of the mammary glands. Therefore, Corpus luteum Secretes progesterone and estrogen.
The purpose of the menstrual cycle is to prepare the body for potential pregnancy. It involves the release of an egg from the ovaries, thickening of the uterine lining, and shedding of the lining if pregnancy does not occur. It is regulated by hormones like estrogen and progesterone.
a week before your missed period
The hormone progesterone in the corpus luteum will prepare the uterus for pregnancy.
The uterus is the hollow muscular organ that protects and nourishes a developing fetus during pregnancy. It is located in the pelvis and has a lining that thickens each month to prepare for a possible pregnancy.
