Why do I get lumps-knots around my ovulation time every month?

The lumps or knots you feel around your ovulation time are likely corpus luteum cysts. These are small, fluid-filled sacs that develop on the ovaries after ovulation. They are a normal part of the menstrual cycle and usually go away on their own within a few weeks.

Here's a brief explanation of what happens during ovulation and how corpus luteum cysts form:

Ovulation: During ovulation, a mature egg is released from one of the ovaries. This usually occurs around day 14 of a 28-day menstrual cycle, but can vary from person to person.

Corpus luteum: After ovulation, the follicle (the sac that contained the egg) collapses and forms the corpus luteum. The corpus luteum produces progesterone, a hormone that helps thicken the lining of the uterus in preparation for implantation of a fertilized egg.

Corpus luteum cysts: Sometimes, the corpus luteum can fill with fluid and form a cyst. These cysts are usually harmless and go away on their own within a few weeks. However, in some cases, corpus luteum cysts can become large and cause pain or other symptoms.

If you are concerned about the lumps or knots you are feeling around your ovulation time, it's always a good idea to talk to your doctor. They can examine you and determine if the cysts are normal or if further evaluation is needed.
