I have found that digitals
are not as sensitive. I just found out I was
pregnant again (2 boys and 1 miscarriage) a couple of days ago which was about 5 days before my missed period. I've always used First Response, however, I have also found that First Response Digitals are just as sensitive as well. Clear Blue Easy is a good digital too, however, for me those ones always show up "pregnant" a day or two after First Response.
Good luck.
