The participants will receive stretching exercise program, 3 days/week for 4 weeks.

The participants will receive same stretching exercises program in addition to myofascial release of cesarean scar, for 30 minutes session twice a week for two weeks.

The participants will receive stretching exercises program for 45 minutes, 3 days/week for 4 weeks.

The pain level of each subject will be assessed during menstruation before participation and after the end of the procedure using the visual analogue scale (VAS) by marker across 100 mm line, Participants were asked to put a mark on the line that they felt represented the most severe pain that experienced during menstruation. The following cut points on the pain VAS will be done: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm)

Assessment will be done by WaLIDD questionnaire that included 1) number of anatomical pain locations, 2) Wong-Baker pain range, 3) number of days of pain during menstruation, 4) frequency of disabling pain to perform their activities, e Each tool's variable provided a specific score between 0 and 3, and the final score ranged from 0 to 12 points (Score: 0 without dysmenorrhea, 1-4 mild dysmenorrhea, 5-7 moderate dysmenorrhea, 8-12 severe dysmenorrhea.

Assessment of abdominal tenderness will be done by using the pressure algometer on day 1 and day 3 of menstruation. A one cm2 pressure probe will be positioned perpendicularly to the skin and pressed at a rate of 30kPa/s on specific PPT marked point on the abdomen around the umbilical scar and lumbar region as follows: Two measurements 4cm from the umbilicus, bilaterally (points I and II), two other measurements 4cm below the previous ones (points III and IV), a single measurement 4cm from the lower margin of the umbilicus (point V) and another single measurement into the medial side of the lumbar region below the fifth lumbar vertebra, corresponding to S2-S4 (point VI).

Participants will be instructed to say "now" when they first felt pain due to the increased pressure. At this point, the algometer will immediately stop and automatically record the amount of pressure applied. Two measures will be collected for each area, with 30s between points testing

The adherometer will be used to measure scar mobility before and after the procedure for each woman in both groups. An adherometer is a clear plastic sheet with concentric circles, with good reliability on measuring tissue mobility of C-section scars in superior, inferior, left and right directions. Participants will lay supine on a plinth with arms at their sides and legs straight. Marks will be made on the CS scar at 2.5 centimeter (cm) intervals using ruler. The examiner will use the marks to measure tissue extensibility in millimeters (mm) in all four directions.
