Getting closer?

This is my first month using opk and let me say it is driving me kind of crazy! Tests are definitely getting darker but wondering if somebody with more experience can tell me if I'm getting close, I know every beautiful woman body is different but I know those of you who have been doing this a while can probably track your pattern in these tests! Predicted to ovulate this weekend so I'm thinking I'm on track! Will post last nights (on top) and today's (bottom)!
