I had sharp pains on CD13, they were really intense and didnt throb, it was just a constant pain. I think it lasted for about 1-1.5 hours. I wasnt too sure what it was, but my workmate said she suffers from O pain and she was pretty certain that was what I was feeling.
im not too sure what the pain has to do with the timing (like if it is before, during or after Oing) but FF thinks I O'd on CD14, which suggests I had the pain before O'ing.
