Has this happen to anyone?

Idk if this has happen to anyone but my LH seems to be going up and down lately… I’ve in the high for about 5 days now and still no peak.. There is one that was getting darker a littte but as I test twice a day it looks like the rest… what can this mean? And no I’m not pregnant I did take a pregnancy test and it’s negative I’m only on CD 7.
