Horrible cramps!! Please please help!!

I am sweating I am hurting so bad. If Ifi move a certain way I get these awful cramps that feel like stabbing pains straight through my lower abdomen to my back. When it starts hurting I can't even move on my own. And on the sides of my lower back. Not just one side both. And the sharp stab pain goes through the middle of my pelvis area to my middle back
