Vfl not darkening
I have a 32 day cycle. The longest cycle I’ve had since I began tracking was 35 days. I’m currently on CD 44. I’m not sure when or if I ovulated this cycle. I’d taken a few test since my period was late but on CD 41 I took another test and got a vfl. Every morning since I’ve taken another one but they all look the exact same with no darkening. Is this an error with the test? The lines show within the testing window and darken over time. Here is a pic of what they look like in the testing window and also dry. Am I pregnant or not?
