Did I already ovulate?

Ashley

Looking at my chart it looks like I ovulated CD8, which is strange. My cycles are usually like clockwork, so I generally ovulate around CD14 or in some cases, 5 days later, CD19. I wasn't using OPKs at CD8 because I usually start just before my fertile window. I have been testing since my fertile window without a peak, but some decent, visible test lines. Do you think I missed out this month?
