I’ve took so many pregnancy tests the last 5 days or so, all cheap ones one 6 day clear blue when it was 6 days before period due. All negative. Today I am due and decided to do my last freedom test strip with my morning urine. After 3 minutes no line at all and left it. Then I went back to bathroom an hour later and there is this? It looks almost dirty so it’s really confusing (I’ve actually cleaned it just to double check). Does this look like an evap line? It’s quite dark which is what is throwing me off the most!
