What Is Ovulation?
How Many Days After Your Period Do You Ovulate?
A woman’s monthly menstrual cycle is measured from the first day of the menstrual period until the first day of the next period. The average woman’s menstrual cycle is between 28-32 days, though shorter or longer cycles do occur in some women.
Ovulation usually occurs between day 11 and day 21 of the cycle, counting from the first day of the last period. Ovulation usually lasts one day, can happen any time during this window, and it’s not always the same each month. Women who have menstrual cycles on the shorter side tend to be more likely to ovulate closer to day 11. Women with longer menstrual cycles may ovulate closer to day 21.
A woman is most fertile in this window when she is ovulating, and women who are trying to become pregnant use ovulation prediction to determine the optimal time to have intercourse, particularly if they are having difficulty conceiving.
Many women use ovulation calendars or period tracking apps to help predict when they will ovulate and be most fertile.
Other methods, including observing cervical fluid, taking daily basal body temperature, and tracking periods can also help you identify when you ovulate.
How Do You Tell If You Are Ovulating?
It may be possible to know when you are ovulating by certain signs and symptoms, such as:
- Basal body temperature increase that is sustained
- Breast tenderness
- Pain or a dull ache felt on one side of the abdomen when ovulation occurs
- Change in cervical fluid
- Change in cervical position and firmness
- Light spotting
- Increased sex drive
- Abdominal bloating
- A heightened sense of vision, smell, or taste
- Elevated levels of luteinizing hormone, which can be detected on an ovulation test
