I took these brands from target 1 yesterday and the other today. The one with 1 blue line is from today and the plus ones the darker one is from today too. I'm just confused if this is an evaporation line? Or if it's truly a BFP? I just find it weird how 3/4 tests have another "positive" line but idk how to determine if it's an evap line or truly a positive line? Anyone had this problem?
