I got my BFPs last night. The frer was visible, but the clearblue digi I had and a tesco digi came up MUCH better, suprisingly. I thought digitals were less sensitive. When I pulled the cartridge out of the tesco one, it was incredibly dark (the test line) the Frer was a thin-but-there line and the clearblue pulled up 1-2 week pregnant. The ICs I used were very faint.x
