10 DPO with a temp spike

[felecia]

If anyone that knows about charting can you please look at my chart and tell me if this temp rise actually means anything? I rarely register anything over 98.0 even throughout the day, I might get a 98.2 but that's about it, but not in the mornings. I didn't have anything different in the temp wise in the house; I even woke up without the blanket on me, which does happen a lot. If anyone could give my insight I'd appreciate it! I used first response, could it just be too early to get a BFP, or do you think I'm probably just and out and my temp is doing something weird?
