Evap right?

I was due for AF 1/3 but I was having brown/pink/red spotting ( enough for only a liner ) for 6 days. Which came 12/27. I didn’t have an actual flow. But while i was spotting little things made me want to cry, my boobs have been hurting so bad for the past month. Even to touch them. I took this test this morning before work, didn’t see anything. I came back home, picked it up to throw it out & saw this. I have neverrrrr had an evap like this on this walmart cheapie. I just want to know if this has happened to anyone?
