Does menstruation ovulate on the first 13 day?
It is normal to ovulate thirteen days after menstruation. The ovulation period of women is closely related to menstruation, and the cycle of both is one month 1 cycle, while ovulation generally occurs in the middle of two menstruation. Although women's menstrual cycle is long and short, the interval between ovulation day and next menstruation is relatively fixed, generally around 14 days.
You can measure your body temperature to calculate the ovulation period, keep enough sleep, don't move when you wake up, don't eat or sleep, keep relaxed and take your temperature. But it takes at least three months to get a clear understanding of ovulation, so this method is basically not used.
Eat when ovulating: asparagus rolls, prepare asparagus, seaweed, grass shrimp and salad dressing. Cook all the food except salad dressing and roll it in seaweed, so that the asparagus hand roll is ready. Salted shrimp, prepare spotted shrimp, salt, wine, ginger slices and monosodium glutamate. Wash the shrimp, put it in a pot and cook it. Remember to add ingredients, so that the salted shrimp can be cooked easily.
What are egg cells like?
In fact, women's eggs are born. When the fetus left the mother and came into the world, there were already 2 million oogonia in the small ovary of the newborn girl, but these oogonia were still immature primordial follicles. Primordial follicles continue to grow and develop throughout a woman's life. Among them, more than 99% of primordial follicles wither and decline one after another soon after they begin to develop, and only less than 1% of primordial follicles can go through puberty, enter the growth period and finally mature into egg cells.
Generally speaking, only one egg cell matures in each menstrual cycle. According to this calculation, from menarche to menopause at the age of 45, more than 500 oocytes can mature in their lifetime. In the process of development and maturation, follicles not only increase in size and vacuoles, but also gradually move from ovary to ovary surface, and finally protrude out of ovarian capsule. When the oocyte is fully developed, under the action of sex hormones and enzymes in the body, the follicular membrane and ovarian vesicle will dissolve and rupture, and the follicular fluid will be discharged, releasing the oocyte. This is ovulation. Women in reproductive period should ovulate once a month.
