The last time it was "that time" for me, I had to practically be dragged to the gym, the whole time complaining that "whoever said exercise lessens your cramps is a liar, or someone that doesn't understand". I did my workout to the best of my ability - and at the end of it said "oh, I actually do feel better now that I've exercised".
It was really hard to get my feet out the door, but I can honestly say I felt better and more energized afterwards. I usually give myself a day off on day 1 (when I'm the most tired/in pain/etc), but day 2 and on I do what I can.
Do something everyday that your future self will thank you for.
