Cramping without a period is called secondary dysmenorrhea, and yes, it's a possible symptom of perimenopause. Some people describe this sensation as “ovary pain.” “Fluctuations in your hormones and cycle length can cause irregular ovulation up until you reach menopause,” Dr. Fiffick says.Aug 3, 2022

I just feel crampy like my period will start soon. It’s not my ovaries though it’s my pubic bone and lower back. And my legs ache.
