Ovulation, as a rule, occurs 12 to 16 days before menstruation, regardless of the length of your cycle. If the cycle is equal to 28 days – ovulation falls just in the middle, if the cycle is more or less, the duration of the first phase (the period before ovulation) varies. How long does ovulation last? ? This formulation of the question is slightly incorrect, since this process represents a single output of the oocyte from the follicle, and it can happen at any time during the day. Definition of ovulation may be necessary for several reasons:
– First, ovulation itself, 3-4 days (so many sperm live) to it and one day after (so much lives a mature egg) – this is a good time for conception of the child: sexual relations during this period give the most guaranteed percentage of pregnancy. And, if a woman can not conceive despite the presence of ovulation, then it is necessary to conduct a serious examination to identify the causes of infertility. Some couples, on the contrary, observe signs of ovulation with completely opposite goals – to avoid unwanted pregnancy. Although, in terms of contraception is not the most reliable way: ovulation can move or occur twice in one cycle.
– Secondly, definition of ovulation is important if the husband has problems with spermogram (lack of mobility of spermatozoa or insufficient number of them). Then it is desirable that intimate affinity occurred no more than 2 days before ovulation, and three days before, there should not be sexual relations between spouses – the concentration of spermatozoa will increase and any of them necessarily”get” to the ovule. !! !!
Some couples watch for signs of ovulation to plan the sex of the baby. It is believed that male Y-spermatozoa are more mobile, but less tenacious, while female X-spermatozoa are vice versa. If the sexual act occurs three to four days before ovulation, the Y-chromosome spermatozoa simply will not survive until the egg matures, hence the couple will have a girl. However, this method does not give 100% guarantee (however, like the rest). But, in any case, the definition of ovulation is important – its availability suggests that the woman`s menstrual cycle is all right.
Basic signs of ovulation
1. Change in basal (rectal) temperature. Perform measurements every day at the same time, without getting up from bed (after 3-6 hours of sleep). In normal, before menstruation, the temperature rises to 0. 5 degrees is a natural reaction of the body to a rise in the blood of progesterone. The day when it falls (by 0.4-0.6 degrees) – and there is a day of ovulation. When measuring rectal temperature, consider that it can be affected by various factors: inflammatory and infectious diseases, hormonal intake, alcohol, etc. If the temperature increase after ovulation persists for more than 2 weeks, and there is no menstruation, then you are pregnant.
2. Change in the nature of vaginal discharge. Another sign of ovulation is abundant discharge, similar in color and consistency to egg white. Sometimes these discharges can be bloody veins – this is not worth worrying about, this is a permissible phenomenon. After ovulation, the secretions of the intravaginal secretion contract and become more dense.
3. Changing the position of the cervix is another characteristic sign of ovulation. When ovulation, the cervix will rise, become softer to the touch, its outer opening has a wide lumen. After the release of the ovule from the follicle, the cervix gradually descends and closes.
Perhaps definition of ovulation by indirect signs: pulling or tingling pain in the lower abdomen, an increase in libido – which is not surprising on the background of the increased level of female sex hormones in the blood. In addition, to determine ovulation allows the overall observation of the menstrual cycle. A regular cycle, accompanied by premenstrual syndrome (weight gain, swelling of the mammary glands, etc.) indicates, as a rule, the presence of ovulation.
For the definition of ovulation at home, you can use test strips and special microscopes. Test strips work similar to pregnancy tests: two strips (even if one of them is pale) indicate a positive result. The determination using a microscope is based on a change in the chemical composition of saliva before ovulation. Saliva is applied to the glass and viewed through a microscope – its specific pattern (the circuits attached to the microscope) indicate the approach of ovulation. More objective methods for determining ovulation include ultrasound, which makes it possible to assess the state of the uterine mucosa and see the change in the follicle, as well as a laboratory analysis determining the concentration of progesterone in the blood.
