I took a test superrrr early (4 DPO) just to prepare myself for the worst. I had left it and in the dim light it looks negative but I held it up to natural light and I can see a vvvvfl. It was a blue dye test if that helps. I’m just not sure if I hold it up the natural light shows accurate results or not. My bf and I both see it but does the natural light show both results or could that be an extremely early BFP?
