When is aunt safe?

Generally speaking, the safe period refers to the period after menstruation, within three or five days, and one week to ten days before menstruation, because this period is not in ovulation, so the same room will not be pregnant, known as the safe period. However, the mechanism of ovulation is due to the influence of the hypothalamic pituitary ovarian axis in the body, inducing the performance of lh peak, thus causing ovulation. The lh summit is greatly affected by the emotions in the body. When in the same room, especially when it reaches orgasm, it may induce the performance of lh wind, thus causing extra ovulation. Therefore, the safe period is actually not safe. In the safe period, the probability of accidental pregnancy is still there, so it is best to do contraceptive measures.
