Exercise and Your Cycle
EXERCISE AND YOUR CYCLE
If you exercise vigorously for 30 minutes, five days a week, the length of time between your periods might increase by up to three days and affect when you’re fertile.
This increase occurs because regular workouts may influence hormones, according to a recent study conducted by scientists at Kaiser Permanente in Oakland, CA.
To keep track of ovulation, you may want to consider using a basal body thermometer.
