I am sorry! You could still get a BFP since your LP is in two days. Do you chart and know if your temp is still up? You could try a First Response Test. I always have had luck with those. Good luck to you. I hope you see a BFP soon.
i'm in the exact same boat. i tested this morning at 12 DPO and got a BFN too. i agree with Beaner, wait another day or two and test again. i think if my temps stay up i'm going to use FRER tomorrow or Friday. GL to you...
