I have my period on the 27th, when is my ovulation?

1. Period calculation method

The period calculation method is one of the most common calculation methods. Based on the number of days in the cycle and menstrual cycle, the risk period can be calculated. The danger period refers to the 14th to 28th day after the start of the cycle. This method is simple and easy to implement, but requires a more accurate understanding of the cycle.

2. David’s formula

David's formula is a more accurate calculation based on a woman's menstrual cycle and body temperature. It considers the Davidic period to be the beginning of the dangerous period, which begins on the 14th day of the cycle and continues until the 28th day. However, David's formula requires a more accurate understanding of cycles and body temperature, so it may not work for all women.

3. Body temperature method

Thermometry determines the risk period by measuring body temperature. Generally speaking, the risk period for women is between day 14 and day 21 of the cycle, but the specific dates may vary due to individual differences. When measuring body temperature, you need to place the thermometer under your tongue and measure for 30 seconds, then record the temperature value.

Calculating your own ovulation isn't the only way. A woman's physical condition and health status will also affect the arrival of the dangerous period. In addition, for some women, the risk period may change due to factors such as mood changes, diet, exercise, etc. Therefore, understanding your own cycle and physical condition and using it in conjunction with other methods is a more accurate and reliable method.

Women's menstrual cycles and physical conditions are different, so calculating your own ovulation date may vary. If you're not sure how to calculate it, try one of the methods above, or ask your doctor or professional nutritionist for advice.
