Well honestly, in that last pic, that would be a negative for ovulation. The test line is no where close to as dark as the control.. So far, I started tracking mine with OPK's and I'm only on cd 12, my lines look similar to the last pic you posted, and I know I'm not ovulating yet, it's just on it's way up. And maybe in your case it's on it's way down.
U probably ovulated the 8th & 9th test days.. because even in the first pic your line was not matching the control, I think it's normal in some women to have faint test lines throughout their cycle. It's just important to distinguish those from the obvious DARK ones, like you said u had on 8-9. So I woulden't worry - Good Luck!!
