Hi Roxanne,
I often have intense cramping and pain right before and after O, especially when we've been BD'ing around O. When my RE did an u/s after O one time, she just found a very large corpus luteum that she thought might be causing the pain. And, it also is more intense for me when I have ovarian cysts or am on Clomid (which seems to then cause cysts...). If it is something new for you, I would definitely talk to your doctor about it.
