Question

what is mensturation circle​

Answer 1

Answer:

The menstrual cycle is the regular natural change that occurs in the female reproductive system (specifically the uterus and ovaries) that makes pregnancy possible.[1][2] The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy.[1] The menstrual cycle occurs due to the rise and fall of estrogen.[3] This cycle results in the thickening of the lining of the uterus, and the growth of an egg, (which is required for pregnancy).[3] The egg is released from an ovary around day fourteen in the cycle; the thickened lining of the uterus provides nutrients to an embryo after implantation.[3] If pregnancy does not occur, the lining is released in what is known as menstruation.
