BFP? But temps dropping...

Danielle

So today is 10dpo according to FertilityFriend and 11 dpo according to Glow. The last two cycles I got my period on day 10 dpo and this morning I have to signs of AF. I have been anxiously holding out to test, but I did this morning and got this with First Response Early Response (below). The only other concern is on my chart my BBT is dropping... any suggestions/ideas?
