I’m 10dpo today and done a frer and easy at home with FMU. They were both negative, but when I looked maybe 10-15 minutes later I noticed this dark line on the easy at home. My partner says it’s an evap line, and I don’t know if I’m just being hopeful but it seems too dark and solid to be an evap line?! What do you think? I’m new to this ☺️
