its possible. my chart was up and down until the day i got that bfp when it went up up up!

tell your DH im gonna kick his butt if he keeps getting you to test early!
i was 11dpo when i got a bfn but 12 dpo i got the bfp. just be patient man! jeez!

as for you, be strong and stand up to him! no testing yet!
