Sounds very likely your friend is pregnant, Veronica! I'm wondering if there's anyone who lives near your friend who might have a spare Lullaby Conceptions early HPT (10miu) for her to try... Of the supermarket brands, I did find First Response was better than Foretel Ultra, I think you can get it at Woolworths.
She should get a darker line in the next couple of days (I predict an appointment at the doctor's Tuesday to organise a BT!) and I'm looking forward to seeing her posting an official BFP soon!
Would love to see those pictures too!
