Here’s how to determine when ovulation has passed:

During ovulation, a woman's eggs are released from the ovaries and travel through the fallopian tubes into the uterus. If a woman is fertilized during this period, the fertilized egg will implant in the uterus and begin to implant within a few days. The process of implantation allows the embryo to begin developing and prepare for pregnancy in the next month.

Therefore, if you want to get pregnant, it's important to know how to tell when ovulation has passed. Here are some tips that may be helpful:

1. Observe basal body temperature: Women can determine their ovulation period by measuring basal body temperature. Basal body temperature refers to the temperature when a woman wakes up in the morning before her body temperature rises. If a woman's body temperature is higher than usual during this period, she may be ovulating.

2. Use a pregnancy test stick: Women can use a pregnancy test stick to determine whether they have been fertilized during ovulation. Pregnancy tests usually show two bars, one indicating fertilization and the other indicating no fertilization.

3. Observe symptoms: Women may feel discomfort during ovulation, such as headache, nausea, fatigue, etc. If a woman feels unwell during this period, she may be ovulating.

4. Measure body temperature: Women can determine their ovulation period by measuring body temperature. During this period, a woman's body temperature usually rises by 0.3 to 0.5 degrees Celsius.

To sum up, the method of judging that the ovulation period has passed may vary from person to person, so it is recommended that women make judgments based on their own circumstances. If a woman is fertilized during this period, it is recommended that she start preparing for pregnancy within the next few days.
