Is this a positive OPK?

Question

This is my first cycle using OPKs, so I'm a newbie to this! The one on the bottom was from this morning. Is that a positive, or should it be darker? Or will I just not know until I've taken one that becomes darker or lighter? 
ETA June 27: Added pic of opk from this morning, and it looks lighter than yesterday's. 😕

Answer

With OPKs the test line needs to be as dark or darker than the control line to be positive. Keep testing. What cycle day are you on? They are definitely getting darker but not close yet. I'd recommend taking them 2x per day in your fertile window that way you don't miss your surge. Sometimes your LH surge can be short and if you only do 1 a day, it's possible to miss it.
