HELP me please.

HELP me please. I'm on day 20 of my cycle and I am having stabbing, sharp pains on the left side of my lower abdomen. They're bad. Like double me over bad. I took pain reliever and it's not helping. This happened last month too and I have the ParaGard. But I've had it for 5 years and this pain is new to me. Any advice?!
