In our professional field, amenorrhea is actually defined as not having menstruation for over six months, or missing three menstrual cycles—this is what we professionally regard as amenorrhea. What most people talk about as amenorrhea refers to the situation where menstruation does not occur when expected. In cases where menstruation does not occur when expected, is ovulation still possible? In fact, it is possible to ovulate under such circumstances.

Generally speaking, for a woman with regular menstrual cycles, if she does not get her period when expected, the first considerations are usually pregnancy or an anovulatory menstrual cycle, both of which are common occurrences. Of course, for women with irregular menstrual cycles, or even for those with regular cycles who do not get their period when expected, it is possible that ovulation may be delayed.

How long can it be delayed? The timing can sometimes be uncertain, it is entirely possible for ovulation to occur sometime after the expected menstrual date. Therefore, during the period after the expected time of menstruation, it is indeed entirely possible for ovulation to occur.
