Why do I have low back pain when I have your period?

Hormones. It is difficult to say for sure, but probably the shift in hormone levels in your system during your cycle. Try to stay active, exercise, use over the counter medications (unless your doctor told you not to use them), and keep going. If you cannot (the pain is more severe), have your gynecologist or pcp examine you.
