How to use an ovulation pen

Patient's question:

No

Doctor's answer:

It is actually an electronic thermometer.
It accurately measures human body temperature and basal body temperature for women's ovulation period, with advantages such as easy reading, precise measurement, and mercury-free. It also features a buzzer alert and memory function.
2. Conversion concept. Typically, the display of an electronic thermometer shows only one decimal place, such as 37.5°C. High-precision models display two decimal places, such as 37.57°C. Therefore, measuring the ovulation cycle based on basal body temperature will be more accurate and cost-effective.
Function: It can accurately determine the ovulation day based on the changes in basal body temperature during the ovulation period. The five days before and four days after the ovulation day are considered the fertile window, while other times are considered the safe period. You can plan for contraception or conception based on different needs.
Method: Start measuring basal body temperature on the first day of your menstrual period and record the corresponding temperature on the test chart. Connect the daily temperatures to form a curve, allowing you to determine the ovulation period based on the graph.
Results:
① For those who are not pregnant:
- The temperature rises by about 0.6°C the day after ovulation (the second day) →
- The temperature remains high for 12 to 16 days (usually 14 days) →
- Returns to the baseline →
- Menstruation occurs.
② For those who are pregnant:
- The temperature rises by about 0.6°C the day after ovulation →
- The high temperature lasts for more than two weeks →
- Seek further medical examination at the hospital to confirm pregnancy.
