6DPO and cramping. Thoughts?

My husband and I have been trying for about one year and a half. We baby danced on June 11 and 12. I was ovulating. Everyday since then I have had cramps. This has never happened before. Not for this many days at least. Hoping this is implantation cramping? What does everyone think? The pain goes up and down with pain depending on what I'm doing to take my mind off it. But tonight it's been pretty bad. I have read it can get worse when actually attaching to the uterus, but I also read it may be too early for that.
