Well as the title says...I'm wondering g what implantation cramping feels like. At about 9 and 10 dpo I had a new kind of cramping I've never felt before. It was very very low in my abdomen, and was a constant dull ache. Not at all like my AF cramps which I get every month right on time. Not sure if it could be implantation cramps or not?? Please help?!?
