2. Common methods for calculating ovulation period
1.calendar method: Suitable for women with regular menstrual cycles.
2.basal body temperature method: Judgment by daily measurement of basal body temperature changes.
3.cervical mucus observation method: Inferred based on changes in the properties of cervical mucus.
4.Ovulation test paper method: Predicted by detecting the peak value of LH hormone in urine.
5.B-ultrasound monitoring method: The most accurate but requires hospital examination.
3. Calculate ovulation period using calendar method
For women with 28-day menstrual cycles:
| menstrual cycle days | Ovulation day | Ovulation period |

| 35 days | Day 21 | Days 17-22 |
| 26 days | Day 12 | Days 8-13 |
4. Basal body temperature method data reference
Body temperature changes during normal ovulation cycle:
| period | body temperature range | Features |
|---|---|---|
| menstrual period | 36.3-36.5℃ | low temperature period |
| follicular phase | 36.3-36.5℃ | low temperature period |

| wet period | increased/milky | medium |
| Ovulation period | Large amount/egg white | high |
6. Usage data of ovulation test strips

|---|---|---|
| 7-10 days after menstruation | 5-20IU/L | low |
| 1-2 days before ovulation | 40-80IU/L | peak |
| after ovulation | rapid decline | Completed |

5.age: Ovulation gradually becomes irregular after the age of 35
8. The latest technological assistance methods
According to the hot topics on the Internet in the past 10 days, the following technological methods have attracted much attention:
1.Smart bracelet monitoring: Prediction based on heart rate and body temperature data
2.Mobile APP algorithm: Analyzing personal cycles through big data
3.Saliva crystal testing: Microscopic observation of saliva crystal morphology
4.Smart toilet detection: A toilet that detects hormones developed in Japan
9. Things to note when calculating ovulation period
1. Record at least 3 menstrual cycle data
2. Combined use of multiple methods is more accurate
3. People with irregular menstruation are recommended to seek medical treatment.
4. Those who need contraception must use other contraceptive measures
