is today my positive OPK??? please respond!

Rachel
These have been taken twice a day for the past few days, the bottom being just now and the one above it this morning 6am. Is today my positive? They all look soooo similar but today's in person is darker than the control. It's only CD12 on Clomid this month which is a few days earlier than normal so I'm not sure what to think! Also have minor "twinges" on my left side and feel "wet" down there! Sorry for TMI.
