The intervention group was first given training on the definition of kegel exercises, diagnostic criteria, treatment, benefits and how to do kegel exercises on the Zoom platform.

A second meeting was held for the participants of the initiative group who could not attend this training.

At the same time, a message was sent to the WhatsApp application group where the intervention group was located three times a day by the researchers to remind them to do kegel exercises in the morning, noon and evening.

No intervention was made in the control group

• Before teaching Kegel exercises, it was recommended that the person empty his bladder and wear comfortable clothing.
• It was said that the person should extend his legs straight while exercising and not to contract his leg, hip and abdominal muscles and not to hold his breath while the pelvic floor muscles contract.
• The relevant muscles were told to contract for 10 seconds and then relax for 10 seconds. The person was also asked to do the exercises during daily activities.
• Exercise was implemented regularly 3 times a day (minimum 30-45 exercises) in the morning, noon and evening.

It was prepared in line with the literature. The form consists of a total of 25 questions, including information about socio-demographic information, pain during menstrual period, vaginal discharge characteristics, and practices regarding menstrual quantity.

It was used to evaluate the pain intensity of individuals during their menstrual period.

Individuals were asked to mark their pain level on a 10-centimeter (cm) horizontal line, meaning "0 (no pain)" and "10 (most severe pain)."

Individuals responded by thinking about the pain they experienced during the first 3 days of their first, second, and third menstrual cycles.

The scale consists of 22 items and is a five-point Likert type. Items 1-13 belong to "Negative effects/somatic complaints" sub-dimension, items 14-19 belong to "Menstrual pain symptoms" sub-dimension and items 20-22 belong to "Coping methods" sub-dimension. The Menstrual Symptom Scale score is calculated by averaging the total score of the items in the scale. Participants are asked to assign a number between 1 (never) and 5 (always) to the symptoms they experience related to menstruation. An increase in the mean score indicates an increase in the severity of menstrual symptoms. The scale has three sub-dimensions. The score obtained from the sub-dimensions is calculated by averaging the total score of the items in the sub-dimensions. An increase in the mean score for the sub-dimensions indicates an increase in the severity of menstrual symptoms related to that sub-dimension. Cronbach's Alpha value of the scale is 0.86

The presence and magnitude of dysmenorrhoeic symptoms were assessed using this Likert-type scale (none = 0; mild = 1; moderate = 2; and severe = 3). The dimensions assessed by the scale are: Colicky pain in the lower abdomen, bloating, irritability, depression pain or tenderness in the breasts, back pain, gastrointestinal disorders headache, leg oedema
