Fist, I am new to this testing thing! So excuse any dumb questions haha. I know that all of these are negative. However, there is little to no fluctuation (8/16am is the darkest thus far) but I am already on CD17, so I feel like I SHOULD be getting close. I was wondering if you all think I should keep testing to see if I ovulate later on in my cycle? If you think I started testing too late and I missed it? Or if I'm likely not ovulating at all this cycle. Any insight or experience would be helpful!

Note: these are kroger brand, and per the kit, the same color or darker indicates LH surge.
