Trying not to get my hopes up..BUT...

So I posted the other day about how my fiancé’s little brother out of nowhere said that their was a baby in my belly...WELL..so today,my daughter got home from being at her grandparents and out of NOWHERE said the EXACT same thing,but I got a negative test this morning and I’m 12DPO,AF is due Tuesday. I’m trying not to get my hopes up but I just fine that odd that they both have said that this week. Should I wait and test in a few days or what? I don’t know what to do that negative this morning brought me down.
