What is the ovulation cycle of a woman with irregular period?

It's confusing. One of the reasons a woman can have an irregular menstrual cycle is because she is ovulating at different times in her cycle. In general women ovulate about 2 weeks after ovulation. If someone ovulates late - her period will come later than expected. That can make trying to figure out when ovulation occurs very frustrating for women with irregular cycles. Please see your obgyn for help.
