Implantation Pain Vs. Ovulation Pain


Does anyone know the difference? Or are the symptoms basically the same.

My opk's have been negative all month (currently on day 16) I've had some elevated lines (day 10 and 11) but None that were as dark as the control line.

Today I'm feeling what I thought to be ovulation cramps. Last night on my right side, this morning on my left. Now it's in my lower back.

Someone mentioned it may be Implantation cramps, not ovulation ... I was just curious if there's a difference.

All women are different so I'm not expecting this to be much of anything but I like learning about all this stuff. I think it's fascinating.
