False negative false positive

Has anyone gotten a positive test (faint but there, not indent, not evap) within 2 minutes. Then next day negative but still a vvfl but start what looks like a period((not spotting)). And again later in the day a false within 2 minutes but dark line 3 minutes. Then not pregnant digital?? My last post got removed due to the photo clearly showing positive below photos were taken within 3 minutes. The all together photo taken within 24 hours but just posted to show difference. The lines haven’t gotten lighter or darker due to time FYI
