Cycle length and ovulation
First of all, we note that ovulation in the female body is an opportunity inherent in nature to conceive a child. The acquisition of the happiness of motherhood begins just in this important period. Without the release of the egg it is impossible to fertilize it with a sperm, it is impossible to conceive a baby.
Each woman with age forms her menstrual cycle. This is the number of days from the first day of the menstrual period to the first day of the next menstruation. Typically, girls have menstruation, or, as they are called, the menstruation starts at 13-14, although today the timing of the onset of menstruation in girls who become physically developed faster are shifted to earlier periods. Sometimes it's 9 years old.
To accurately determine the duration of ovulation, you need to know exactly the duration of your menstrual cycle. Its normal length ranges from 21 to 35 calendar days. Cycle for various reasons can shorten or lengthen. Sometimes it occurs and failures.
Ovulation in the menstrual cycle occurs only once. This happens in the middle of the cycle. If it lasts 28 days, then the egg leaves approximately on 13-14 day. This is the date of onset of ovulation.
How does ovulation occur?
In every ovary of a woman there are follicles. These are small vesicles that ripen every month in one of the ovaries. Completely ripened "bubble" in diameter is up to 24 mm. Such a follicle is dominant, that is, it is from it that a mature egg leaves during the period of ovulation.
The first phase of the cycle is called the pre-ovulation phase. During this period, the follicle undergoes changes. In it, under the influence of estrogen, the level of luteinizing hormone increases. The second phase is ovulatory, when the follicle bursts and the egg leaves. How long does the period of ovulation last? It's about 48 hours. At this time the female cell is waiting for fertilization, it is ready for conception, hitting the uterine (fallopian) tube. There she awaits her future destiny, which provides for two options - fertilization or infertility. If within these 48 hours a sperm enters the fallopian tube, it moves to the egg and tries to penetrate it. In a healthy sperm it works. The process of the fusion of the egg and sperm continues by dividing the cells, that is, by conception.
When the ovum does not wait for fertilization, it simply dies. Then, together with the layer of the endometrium, it is rejected - and menstrual bleeding occurs.
The systematic nature of the onset of ovulation
Does the ovulation always occur with a regular menstrual cycle? Gynecologists have the concept of anovulatory cycle. This is a cycle when ovulation simply does not happen. And this happens in quite healthy women. In most cases, ovulation occurs monthly, but anovulatory cycles occur 2-3 times a year. Ovaries can simply "rest", in them the follicle does not ripen.
You should also know that ovulation can be late and early.
For example, in the 28-day cycle, it may occur on day 8 and 18.
Ovulation bias is most often caused by stress in women today. This is noted by specialists. Also, ovulation offsets occur due to malnutrition and the rhythm of life, diseases, and the intake of hormone-containing drugs.
Symptoms of ovulation
Different women experience different signs of the onset of this important period. About 20% of girls note, that for them it is a rather painful process.
Ovulatory pain resembles menstrual pain, but it is not so strongly pronounced. Some girls suffer from pain with ovulation cramp character, others they pull, and still others do not feel anything at all. Ovulation is sometimes accompanied by dizziness and nausea, fever and weakness. This is more typical of nulliparous women.
The degree of soreness of ovulation affects the health of women, the general condition of her body.
