17dpo and i had twins. bfn everyday until i saw a super faint line... 11dpo is considered early, i know most ladies will start testing at like 7dpo and im sorry but they are crazy i've only known a handful of gals who got lines that early. sometimes you don't even implant until 11 or 12dpo! then you still have to wait a few days to build up enough hcg to be detected. you aren't out, good luck in the next few days.
