Implantation pains

Katie
Has anyone ever experienced implantation pains/cramps? Last night I had a pain in my lower abdomen that I've never experienced before! It was 5-10 seconds long and happened twice in a 2 minute time frame. It was almost like a quick, stabbing pain. I was 8 DPO last night, 9 DPO today.
