please don't be offended but this sounds possibly like some hormones talking. I think you are having a down swing right now. Remember, there is really no way to know. Even if you did conceive nothing would have even implanted yet so there is no way to know at all!
As for soar or CM there are sooo many other factors... don't give up now!
Honestly, I think you are just setting your heart up for a negative, which is fine and totally understandable, but there is no way you are out of the game yet.
Give yourself a few days, you might feel better as things level out.
