When you can not get pregnant?
Probably, it is not a secret to anyone that a woman can get pregnant far not every day. So, the opportunity to conceive a child exists only in the middle of the menstrual cycle, in the period called “ovulation”. It is on these days that the female egg ready for fertilization "waits" for the spermatozoon. Note that every representative of the beautiful half of humanity ovulation occurs on different days. It depends on many factors and on the individual nature of a particular organism. The difficulties of determining the time when you can not get pregnant are connected with this.
On average, in a healthy woman, the menstrual cycle lasts for 28-30 days. Ovulation usually falls on the 12-16th day. If the cycle of a particular woman is shorter, the egg cell is ready for fertilization earlier, if longer - later. Given all the above, it can be determined that the safest are a few days before menstruation and after menstruation.However, there is not much to be under a delusion here either: ovulation may occur sooner or later, not in the same way as last month. After all, the menstrual cycle depends on many factors. It is affected by food, stress, daily routine and much more.
Today, there are many ways to determine the time of ovulation. Knowing this, you can more clearly highlight the days when you can not get pregnant and those days during which the probability of fertilization is highest. The most accessible way to determine the time of ovulation is the basal method. It consists in the regular measurement of temperature in the rectum and the independent construction of special graphs. However, this method cannot be considered accurate.
More reliable ways to determine ovulation are ultrasound (ultrasound) and special tests. The disadvantage of these methods can be considered financially motivated, since both a visit to an ultrasound examination room and the purchase of tests at a pharmacy require certain costs.
