Period due tomorrow - took Sainsbury’s early pink dye this morning on FMU. Completely blank after 3 mins but at 5 mins my husband saw the test and said huh?? We see a line! The test said read results in 3 mins and disregard after 10 mins? I know the only option is to do another test tomorrow but I’m feeling impatient!! Is it worth doing another test today? Is this just an evap line. Only first month of TTC baby no2!
