what are my chances?

I'm 9-10 DPO because my LH dropped at midday on the 8th (though LH surge was the 6th), AF due today, no signs only the odd very light twinge of cramp but sort of off to the left, whereas AF are always central and low, and very light back pain that comes and goes. 
Here's the thing though, since yesterday afternoon I've been having waves of light nausea which is absolutely not normal for me. I've been testing for a couple of days and BFNs. I know that ultimately it's a waiting game and I'm trying not to get my hopes up... but it sounds promising, yes? What do you think my chances are?
