It is helpful for couples planning a pregnancy to know which days are most fertile, although this is not necessary with regular intercourse. To determine the time when fertilization is most likely, several methods are used - the Ogino method, the temperature method, special tests.
Instructions
Step 1
The Ogino method allows you to calculate the time of ovulation in a woman by tracking the menstrual cycle. The average female cycle lasts twenty-eight days, and ovulation occurs in the middle of the cycle. But in fact, the cycle often gets lost under the influence of various factors, sometimes ovulation may not happen at all in a certain month, and sometimes it happens twice per cycle. Therefore, Ogino's method is based on the duration of the last twelve cycles.
Step 2
Keep a calendar of your periods throughout the year. Determine which cycle in the last year was the shortest, and subtract 18 days from this number. The resulting number, taken from the beginning of the cycle, will be the first favorable day for conception. Then subtract 11 from the longest cycle to get the last day. For example, if the shortest cycle lasted 26 days, and the longest 32 days, then from the eighth to the twenty-first day of the next cycle there is a good chance of getting pregnant.
Step 3
Determine the day of ovulation, that is, the most favorable for conception, using the temperature method. To do this, you need to measure the basal temperature every day in the morning using a conventional thermometer. Typically, the basal temperature of a healthy woman is 37 ° C, but due to the increase in progesterone levels during ovulation, it increases. After that, the egg is released for another two to three days, so this time is also favorable for conception. But the temperature method is not always accurate, since the basal temperature can change with insomnia, anxiety, colds.
Step 4
One of the most accurate ways to find out favorable days for conception is to use ovulation tests. Buy these tests at the pharmacy, they are similar to pregnancy tests. Use the test five to six days or less before the expected ovulation. Follow the instructions and at the end look at the strip - if it becomes as bright as the control one, then ovulation will occur within a day or a day and a half.
Step 5
The most reliable way to determine ovulation is to do an ultrasound scan, which can monitor the release of the egg. There are also methods that help to find out favorable days for conception and based on the intensity of saliva crystallization. Do such an analysis at a clinic or buy a device for home use.
