12 dpo and bfn! So disappointing :( am I out?

Delsie • Momma to Jagger ( 3 ) & finally expecting baby #2 OUR rainbow - April 20th,2016!! After 3 loses I'm so nervous! :/
Such a sad feeling to get a bfn expectially on a FIrst response when they are suppose to detect as low as 6 hcg , I was really crampy around 8-9dpo.. Thought maybe implantion but if so I should have enough hcg to trigger a + by now id think.. Hoping AF don't show her face but cervix is getting low and hard so doubt BFP this month :'(
