10/11 DPO BFN?

Feeling discouraged I have been testing early (I know I shouldn’t) but got what I feel like was a BFN this morning with FMU...shouldn’t I have SOMETHING on a FRER at this point since they’re the most sensitive? I’m either 10 or 11 DPO and have been having mild cramping, hot flashes, and sore boobs (I know all of these can just mean AF is coming).

Did anyone get a BFN at 11DPO and went on to get a BFP?
