Yeah it looks lighter if anything to me. Can you take a pic of today’s next to yesterday’s? I know you say it takes a long time for your tests to darker but I really think you’d have a clear line by now if it was a new pregnancy. You said you didn’t want another tho right so I think you might be ok! Strange you keep getting fluctuating levels of hcg tho and I don’t have an answer. Maybe your post partum body is doing strange things? It could be worth going back to doctors tho and showing the more recent tests you have?
