Excruciating cramps when pooping

So I started my period this morning, it's pretty regular flow for me, and it's now the evening so I went to go poop and when I did I had a horribly painful cramp/shooting pain in my abdomen.

Like so bad I bent over and nearly cried out.

Have any other girls experienced this is this quite a normal thing to happen? I know during your period all your organs down there get a bit sensitive.
