Here's how to determine when you're ovulating:

1. Observe symptoms: During ovulation, women may feel abdominal pain on one side, accompanied by a small amount of vaginal bleeding. These symptoms may disappear within a day or may last for a few hours.

2. Measure your body temperature: You can determine when you are ovulating by measuring your oral or anal body temperature. Typically, during ovulation, body temperature rises by 0.5 to 1 degree Celsius.

3. Use test paper: Test paper can detect a woman’s hormone levels during ovulation. If you're thinking about getting pregnant, a test strip can be a helpful tool.

4. Observe basal body temperature: Basal body temperature refers to the basal body temperature of a woman when she is awake. By recording your basal body temperature, you can determine when you are ovulating.

All of the above methods can help determine when you are ovulating. If you're unsure, talk to your doctor or professional nutritionist. During the ovulation period, I wish you a good pregnancy!
