I did a FR yesterday and there was SUCH a faint line on it, I wasn't really sure it was even there. Over time (that is, after the time limit had passed), it darkened and become more obvious, so now it's a nice pink line you can see from a distance without squinting etc.
Since then, I've done some other brands (clearblue, asda, savers & ebay strips) - I get very faint but reasonably obvious lines on the cheaper tests (ebay and savers) but I'm doubtful whether the VERY faint hint of lines I see on the CB and Asda tests are anything more than my imagination ;)
Any advice? Do FR tests have a habit of developing nice lines when they're really negative? I've only ever had stark white ones before - even WAY after the test expired - but I'm reluctant to believe thsi line when the other brands are negative.
