What causes this leg pain during my period? - leg pain causes

Whenever I have my period, I have pain in my thighs, almost like a pain in my veins. It comes and goes, during the worst days of my time and sometimes in the day, if you do, but not as painful. I am 40 years old, and it just a few years. Thank you!
