10 dpo vvvf test

adams
I am 9 or 10 dpo. I took a equate + - came out faint positive within time frame then i took a first response was negative that i seen is it possible it is to early for a first response? Dont want to give uo my hopes as yesterday two came out faint positive on the two line test that are blue dye. Could it be that i am starting to just now have hcg producing for why the first response isnt showing positive?
