I find that just before my period, my muscle aches get much worse in about everything below my waist; legs, ankles, and feet. In a good mood I think about how, thank god, I don't need to worry about getting providing for a small child, as well as myself. On bad days, I find it hard to get enough energy to make it through to movements to get to class. And I also feel like verbally abusing anyone in sight. Immature though it is, I just sometimes want to crawl back into bed, and never come back out.
