You need to release an egg every month only when you want to conceive (become pregnant). You are “normal,” meaning you and many other millions of women like you are infrequent (about 5-6x) ovulators, meaning your ovaries do not produce an egg every month. Therefore, there isn’t any need for your uterine lining to flush/washout/menstruate/shed the non-fertilized egg. You’ll be fine, don’t worry.
