Yep= sounds like ovulating to me...
Have you ever had break-through bleeding that occurs in the middle of your cycle? That is what it kind of sounds like to me. Some woman also have a little bit of spotting during ovulation time, so it might be that as well. That could also explain the crampy feeling. I used to get horrible twinges in my ovaries when it was "o-time"!!
Just keep bd'ing!!! Good luck!
