So, tested yesterday evening. Period is due on Tuesday (2nd). Got a very, very faint line (see attached photo). Tested again just now (impatient and didn't want to wait for FMU tomorrow!) and got a very faint line just like yesterday's. Was visible within the three minutes albeit squinting. Lines are virtually the same, though - today's isn't darker.
I've read that FRER sometimes have indent lines or evap lines - anyone want to proffer a guess as to whether it's a positive or an evap line? Or, given how faint it is, is it more likely a chemical pregnancy?
Many thanks.
