Why can’t I have cramps like normal people?

Right before my period up until I finish my period my legs ACHE so bad. It’s feels like I’ve been lifting weights with my legs; so sore, so achy, and they’re warm too. I only get this around and during my period. Today I stayed up all night because of the pain. They’re just so sore 😥

The pain runs from my thigh to my ankles, but the pain is worse around my calves.

Why am I like this? I don’t get cramps in my stomach unless I’m passing blood clots during period, otherwise my legs suffer.

Is this normal? Is anyone else’s like this?

I also try to stretch my calves as much as possible.

I do lack vitamin D. I don’t know if that affects it or not. VD lvl is 9. Normal level is anywhere between 30-100
