Determining Ovulation. Given that you have a regular cycle, no matter whether it is short or long, you know the period of ovulation – in a normal 28-day cycle it is between 14th and 17th day, counted from the beginning of the last menstrual period. In a short cycle of 22 days the ovulation is between the 8th and 11th day. In a long cycle, 35-day cycle, the ovulation is between 21 and 24 days.
Determining Ovulation – There are many signs by which to determine imminent ovulation:
– Tension of the chest, as a result of devoting more estrogens, which precedes the separation of the egg.
– Slightly pressing in the area of the ovaries.
– The appearance of vaginal mucus with no smell or color produced by cells in the cervix. This cervical mucus is abundant between 10th and 14th day of the cycle. It is an excellent environment for reception of sperm, thanks to it they can penetrate inside the uterus and fertilize the egg.
– Possibly slightly bleeding.
But these signs are not required to say that there is ovulation. They may be noticed in some women, while others don’t experience them. Ovulation is usually confirmed unconditionally and with absolute certainty only by examination with a vaginal ultrasound. However, the change in the concentration of hormones in the blood and receiving ultrasound picture can provide conclusive evidence as to whether or not there was an ovulation during the cycle.
Are there reliable methods for determining ovulation?
If your period is irregular, then ovulation is also irregular. To find it you can use several methods that will show ovulation by measuring basal temperatur, by monitoring the consistency of cervical mucus or by using home tests for ovulation (such are the tests for pregnancy and sold in pharmacies).
Determining Ovulation – Method of basal temperatuar
Internal body temperature is amended during the menstrual cycle (in this case under the menstrual cycle means the period from the first day of bleeding to occur next). The temperature curve of the menstrual cycle consists of a first part in which it is below 37 degrees. This is follicle phase during which becomes dominant follicle maturation. When the cycle is normal, 28 days, on the 14th day suddenly has a lower temperature. This is the time of ovulation. Even the next day, the temperature again is increased to exceed over 37 degrees. This second part of the curve is called the luteal phase and then the temperatureremains above 37 degrees by the next early menstruation. Unlike the first phase of the cycle that pulses and is not a constant length, luteal phase is constant for every woman. For different women it may vary between 11-14 days. Luteal phase shorter than 10 days prevents implantation of a fertilized egg, ie short second phase of the cycle may be the reason for infertility.
Ovulation is the day with the lowest temperature before the days of persistent high temperature. This means that ovulation date is known, only if there was ovulation. If the curve remains unchanged – no temperature increase, so there was no release of an egg and therefore there was no ovulation. If there is a fertilization, the temperature will remain above 37 ° C during the first 2-3 months of pregnancy.
