Not pregnant but a question for you guys.

For any of you that experienced implantation cramping what did it feel like? And where exactly did you feel it? 
Ever since about 5-6 dpo until now 9dpo I have been having these off and on almost tight feeling pinch pains. On my lower right and sometimes left above my pubic bone. The worst one was 6dpi that felt sort of like a pinch and pull while I was laying down. They are super painful.  But enough to notice. Now 9dpo I'm noticing when I cough (I have a bit of a cold/sore throat) that I can feel a little pinch/tug in the same spot. 
I was wondering what you all felt?
