Ovulation refers to the time when eggs mature and are released from a woman's body, usually between the 14th and 19th days of a woman's menstrual cycle. For women who want to have children, knowing their ovulation period can help them better plan their reproductive plans.

So, how to determine your ovulation period? This can be determined by:

1. Measure basal body temperature: Women can measure their body temperature when they wake up every morning and record it in a table. Basal body temperature refers to the basal body temperature produced by the body when it is cold at night, which can help women determine their menstrual cycle and ovulation period.

2. Observe symptoms: Some women may experience symptoms during ovulation, such as changes in appetite, increased energy, tender breasts, protruding nipples, etc. If you feel these changes, you are probably ovulating.

3. Use a pregnancy test tool: If the above methods cannot determine your ovulation period, you can use a pregnancy test tool to determine it. Generally speaking, pregnancy test kits can detect pregnancy on the 10th or 14th day of a woman's menstrual cycle.

A woman's menstrual cycle and ovulation period are affected by many factors, such as stress, diet, medications, etc. Therefore, if you are unsure about your ovulation period, or if you want to have children, it is best to talk to your doctor or a reproductive health professional.
