I’ve taken a total of 4 frer pregnancy test, the first one was completely negative, the last 3 looked like they all had a vvvfl on them. I threw two of the three away, and forgot about the 4th one. It’s been about 2-3 days since I had taken it. And it has completely dried out, I looked at it and it has a pink line on it.

Can indent/evaps turn pink after drying?
