What is late ovulation?
First, let’s look at the definition of ovulation. It's when a mature egg is released from your ovary due to certain hormonal changes and begins making its way to your uterus through a uterine tube, where it may be fertilized by a sperm. Typically, ovulation happens about 14 days before the start of your next period, which is the middle of your overall 28-day cycle.
Most women actually ovulate between day 11 and day 21 of their cycle, not necessarily on day 14. It usually depends on the length of the follicular phase, which normally ranges from 10 to 16 days. As the length of the luteal phase is constant, the phase lasts for about 14 days. Ovulation is only considered late if it occurs after day 21.

While it’s not always an issue, late ovulation can sometimes cause problems. Ovulation disorders account for infertility in 25–30 percent of couples who can’t conceive. However, late ovulation doesn’t mean there won't be any ovulation. Sometimes it’s just a waiting game.
