Progression opinions?

Victoria

This is my first time posting and my first time ever using OPK tests. I've used the first response ones around late morning, for several days and I know they aren't positive but this morning using FMU I tried a dollar store test that looked more positive to me. Followed that with the FR test at the normal time I had been doing and it looks even lighter than yesterday FR. I'm so confused. Anyone have any opinions?
