Running before my period makes cramps worse? ?

I usually avoid running when I’m due my period however I felt like it today even though I had very mild cramps this morning.

I went for a run at normal pace and distance but I was met with the worst cramp upon completion of the run I had to curl in a ball when I got home until it passed (after a few minuets then was fine again).

Is it normal for running to cause cramps to get worse? (I never have cramps any other time during the month during, before or after exercise so I assume it’s linked to my period).
