Is this a positive ovulation test? I know the rules of an OPK, but it's dark in some areas and light in others.

This is from last month. The reason I'm asking now is because I have been off the depo shot for about 7 months now, and I read that some women don't ovulate for years after the depo. That made me question what this was. Thanks!
