What is fertile day? There is a period before and after ovulation, during which the probability of conception increases dramatically. These days are called fertile. At this time, the egg is completely ready for fertilization.
How to determine the fertile period
Of course, the very understanding of what a fertile day is is not useful in practice. But if you know how to determine these most favorable periods for conception, you can protect yourself from unwanted pregnancy or, conversely, increase the likelihood of conception of a baby.
There are two ways to determine the onset of the fertile period.
- By the color of the selection. Before ovulation, the mucus of the uterus becomes less thick and transparent. It is saturated with salts, glucose and proteins, resulting in an environment ideal for sperm.
- By body temperature. Before ovulation, women's basal body temperature rises by several degrees due to an increase in the level of the hormone progesterone. It is best to determine the temperature in the morning before getting out of bed. It is recommended to take measurements several months in a row for more accurate results.
It is worth noting that the fertile day of the cycle can shift under the influence of adverse factors - such as lack of sleep, stress, alcohol and others.
How to measure basal temperature
Basically, basal temperature is determined in the rectum, but it can also be measured in the mouth or vagina. It is necessary to use the same thermometer and carry out the procedure every day (including during menstruation), at the same time.
Calculation of fertile days
To understand what a fertile day is and how to determine it correctly, you need to know exactly when you will ovulate. The most suitable time for conception is the last day before ovulation. And there is a logical rationale for this - the egg is ready for fertilization in just a third of a day, and spermatozoa exist for one or two days, no more. And you need to accurately calculate when the conditions favorable for conception coincide.
First you need to keep a schedule of your menstrual cycle. This will help determine when you will ovulate. And already guided by it, you can easily calculate your fertile days. You can get pregnant more likely around the middle of the cycle. Suppose, if its duration is 28 days, then ovulation will occur on the 14th.
Rules for calculating fertile days
- The course should be monitored for at least three to four months, and sometimes more, depending on the regularity of menstruation.
- The number of days in the longest menstrual cycle should be subtracted 11. The resulting number will be the last fertile day of the cycle.
- Further from the number of days in the shortest cycle you need to subtract 18. As a result, you will get the last fertile day.
If you know exactly what a fertile day is and how to determine it, then your chances of getting pregnant will increase many times over. The effectiveness of this calculation method reaches 85-90%.
