In brief: Ovulation

Ovulation usually occurs 12-16 days before menstruation.
If your typical menstrual cycle length is 28 days, ovulation usually occurs on day 14. If your cycle length is 32 days, ovulation would be on day 18. You can predict when ovulation will occur by using urine ovulation predictor tests available in most pharmacies. They turn positive about 1 day before ovulation.
