Xiaohui is a young woman who often worries about whether her ovulation period is normal. When she was younger, she took some medications to improve her fertility problems, but the results weren't always good.

Xiaohui started using calendars and calculators to calculate her ovulation dates and have sex as planned. She'll also try some emergency contraception to make sure she doesn't get pregnant.

However, Xiaohui realized that her ovulation dates were not entirely accurate, especially if she was taking certain medications. She began to worry that her ovulation might be affected by other factors, such as stress, mood and health.

Xiaohui decided to seek professional help. She found a doctor for an examination and consultation. The doctor told her that her ovulation could be affected by a number of factors, including medications, lifestyle and health conditions.

Xiaohui began to realize that she needed to take some steps to ensure that her ovulation period was accurate, such as exercising regularly, maintaining a healthy diet and sleep, and reducing stress.

Xiaohui's ovulation periods became more accurate and she had sex more easily, increasing her chances of having a baby. She credits doctors and calendar and calculation tools for helping her better understand her body and nature's patterns and take appropriate steps to ensure her health and happiness.
