Yeah. I usually get pain from 1-2 weeks BEFORE the start of my period.. then during.. then maybe a week after. But I still get it randomly during normal days of the week. I use a heating pad when it hurts. That helps the pain for me for a while.
They can "act up" at any time. I had worse pain at both mid-cycle and just before my period. But, I have cysts cause me pain all times of the month.
