Is something wrong?

I got a vfl yesterday on 4 tests but the darkness verys on each of them. I tested again this morning with fmu and it wasn’t any darker, almost lighter? I technically haven’t even missed my period yet, but the line is there I stg. My husband sees it but he’s reserving his excitement until it gets darker. We’ve been trying for months now with pcos and I’m worried it’s not true. Based on my last period, I’d be almost 4 weeks exactly. Is it still just early? My tests aren’t expired and I even compared to old tests for evap/indents but there aren’t any. There’s color to the positives I got today and yesterday. Am I crazy for celebrating?
