My period is on the 18th, when is the ovulation date?

Generally speaking, a woman's menstrual cycle lasts 28 days, but it varies from person to person. Most women will begin to release eggs on day 14, while women with longer menstrual cycles may release eggs on day 16 or 17. Therefore, if your period comes on the 18th, your next period will be around February 22nd.

The timing of your menstrual cycle and egg release is affected by many factors, including diet, exercise, stress and health. Therefore, everyone's cycle is different and may fluctuate over time.

If you want to know the exact date, it is best to consult a doctor or medical professional. They can measure your temperature and observe your menstrual history to provide you with more accurate information based on your personal situation.
