How to determine ovulation at home?
Knowing the exact timing of ovulation allows women to control the fertilization process or protect themselves from it, if they do not want to have a child. Approximately in the middle of the menstrual cycle, ovulation occurs - the release of a mature egg into the fallopian tube, where during the day it has the opportunity to fertilize with a sperm.

Determination of ovulation using a test
In a woman's body, there is always a small amount of human luteinizing hormone (LH), which increases significantly one day before ovulation. It is most easily detected in urine and blood. To determine the date of ovulation, you can use a one-time test, the action of which is based on comparing the concentration of LH in the urine with a control value.
The test is used in the same way as a pregnancy test, but it must be performed daily for a certain period after your period, so this method is not cheap from the financial point of view.
Ovulation test rules:
- Do not urinate for 4 hours before using;
- Drink liquid to a minimum, so as not to reduce the concentration of the hormone in the urine and not get a false result;
- Dip the tip of the test strip into urine for 20 seconds, or hold it under a stream of urine for 5 seconds, wait 3 minutes.
After the required holding time, the results obtained should be evaluated. Criteria for evaluation:
- The manifested strip is lighter than the control one - there was no ovulation, so the LH level remained low;
- The manifested strip is brighter than the control one - the LH level increased sharply, 24-36 hours remained until ovulation.
If, within 2 days after the release of luteinizing hormone, sexual intercourse is performed, it will most likely end with the conception of a child. After fertilization of the egg, it is pointless to continue testing.
A reusable test, which is a device with a set of test strips, works in a similar way. Using it, you can test up to 20 times a month. The device shows the date of the onset of ovulation, the periods in which the probability of fertilization is most likely, the periods when you can not use contraception, because the woman has a low fertility rate at this time.

Calculate ovulation calendar online
Using this calendar, you can find out exactly the day of ovulation, the days most suitable for conception and the days of least fertility.
To use this computer program, please provide the following information:
- Day of the beginning of the last menstrual period;
- Duration of the menstrual cycle;
- The duration of your period.
The method may have an error if it is used by a woman with an irregular cycle.
Calculate ovulation
How to determine ovulation by basal temperature?
Using this method, you need to measure the temperature in the rectum or vagina every morning at the same time. For the measurement, an ordinary mercury thermometer is used, which is kept for 5-7 minutes to obtain an accurate result.
To avoid inaccuracies, you need to keep a thermometry diary for several months, where all the results are scrupulously recorded. The measurement time was not chosen by chance, because at this time the most accurate results can be obtained. The time of ovulation is determined by a jump in temperature by a few tenths of a degree upwards in relation to normal values.
Example:
- From the first day of menstruation, the basal temperature values were in the range of 36.1 ° C-36.6 ° C;
- From day 13 this value was equal to 36.6 ° C;
- In the morning of 14 days, there was a jump to 37.3 ° C, therefore, ovulation occurred.
- Your basal temperature will be elevated until your next period.
Women with a well-established cycle can accurately calculate the days of the upcoming ovulation even before this process begins.
How to determine ovulation by discharge and sensation?
Normally, in the cervical canal of the cervix there is a certain amount of a special secret - cervical mucus. It is quite thick, but at the time of ovulation, the mucus becomes more liquid, stringy and watery. If you stretch it between your fingers like used chewing gum, you get a kind of thread up to 10 cm long. During ovulation, the volume of vaginal discharge increases.
Attentive women can determine the moment of ovulation by their feelings.
They do not need to use test strips, take tests, it is enough to analyze the following signs:
- There are aching pains in the lower abdomen;
- The mammary glands are swollen, tense and slightly painful;
- Emotional instability, irritability is present;
- Increased libido;
- A small amount of spotting may appear;
- The abdomen is swollen due to flatulence.
A combination of 2-3 signs of the above symptoms indicates the onset of ovulation.
How to determine ovulation with an irregular cycle?
Most accurately, the time of ovulation with an irregular cycle is determined using a daily ultrasound scan. During an ultrasound scan, the doctor accurately determines the date of release of a ripe egg from the ovary, because he is able to track the process of growth and maturation of the follicle, to see the moment of follicle rupture.
Daily monitoring can be done to determine the most favorable time for conception if the spouse is undergoing fertility treatment or has a low chance of fertilizing an egg.
Determination of ovulation by crystallization of saliva
If you prepare a preparation from female saliva during ovulation for examination under a microscope, you can see how the secret crystallizes, taking the form of a fern leaf. These changes are called "fern syndrome" and are the result of hormonal changes that crystallize saliva in such a bizarre way.
Determination of ovulation by the level of progesterone in the blood
With the onset of ovulation in the female body, the level of progesterone increases sharply and remains at this level until the start of the next menstruation. If you measure this level several times from the beginning of the cycle, you can determine the date of ovulation by the jump in the level of the hormone in the blood.
Applying in practice methods for determining ovulation, you need to remember that the ovum remains viable for a day after leaving the ovary, and the sperm for 4-6 days.
