Disbelief

H?
What are the chances?
I took a FRER yesterday with FMU at 9 dpo and got a BFN, today (10 dpo and NOT FMU) I took a first response gold digital and it says "YES+". Of course I am thrilled, but I'm cautiously optimistic...especially with yesterday's BFN. 
Thoughts? 
Only sort of freaking out. 
Here is the pic of yesterday's test and today's test test. 
PS- that is my husbands hand, not mine! Haha
