Yes, temporary anovulation is known as intermittent anovulation. This is most common around the time of your first and last periods. Intermittent anovulation can also be caused by stress, weight changes, and illness, so there are lifestyle tweaks you can make to encourage ovulation.  If you haven’t ovulated for 12 months, this is known as chronic anovulation. Contact your doctor to discuss treatment options for this as soon as possible. If you want to get pregnant, you’ll need to treat your anovulatory cycles first.
