How to ovulate
Ovulation in women of childbearing age usually occurs at 12-16 days before beginning of menstruation, i.e. approximately in the middle of a 28-day menstrual cycle. Phase of the cycle preceding ovulation, called follicular, or estrogen. Its length can vary from 7 to 22 days, although in some cases (usually, abnormal) it can reach 40 or more days. In the follicular phase under the influence of hormones going on oocyte maturation and growth of the follicle, where it subsequently leaves the ovary. Release of an egg from the ruptured follicle is ovulating. Day in which it occurs, is most favorable for conception.
Also considered fertile 3-5 days before ovulation and the day after.
The second phase of the cycle is called the luteal, or corpus luteum phase. At this time, the egg moves to the uterus to the fallopian tube. If fertilization has occurred, for 5-10 days the embryo is implanted in the uterine wall. If conception has not taken place, the egg dies within days. About two weeks later under the influence of hormones is rejected inner lining of the uterus - the endometrium that outwardly appears as a regular menstruation.
One of the common mistakes during pregnancy planning is an attempt to mathematically calculate ovulation or feelings. Count the days - often a futile exercise. Is much more reliable to determine ovulation by means of tests, follikulometrii (US) or, in extreme cases, by using basal body temperature chart.
Also, do not attempt to calculate the impact of ovulation on the child's sex. Despite the "scientific basis" of such theories in life, they are not always triggered.
The reasons for the lack of ovulation
Pregnant if no ovulation impossible. The most common cause of her absence is hormonal failure in the body. Also, problems with ovulation may occur after long-term use of oral contraceptives. In most cases it is treatable. Achieve ovulation or you can bring it with hormone therapy.
May be absent ovulation in women with excessive or underweight. Special treatment in this case is not required. Once back to normal weight, problems with ovulation usually disappear.
After 40 years of ovulation becomes irregular, and therefore get pregnant at this age is difficult enough. Hormone treatment in this case is not always successful.
