Early ovulation is when an egg is released from an ovary earlier than is expected in an average cycle. Early ovulation may occur due to several factors such as stress or a shorter menstrual cycle.

Is it bad to ovulate early?

Early ovulation has sometimes been thought to signal a less fertile cycle. For example, some authorities state that a cycle is seldom fertile when ovulation occurs before day 13 of the menstrual cycle. We found no evidence of this. Indeed, the earliest ovulation in our study (cycle day 8) produced a healthy infant.

What's the earliest you can ovulate?

Many women typically ovulate around 12 to 14 days after the first day of their last period, but some have a naturally short cycle. They may ovulate as soon as six days or so after the first day of their last period. And then, of course, there's sperm.
