I got this very positive digital test

The next night I retested with a digital clear blue again it said ‘not pregnant’ then this morning I tested with fr digital which said ‘no-‘

I feel very sad and I don’t want to get in a funk. I’m so confused and want to be pregnant more than anything.

I’ve been trying for 7 years and to see the ‘pregnant’ reading & it changed to not pregnant the next day is concerning anyways I’m rambling I just need reassurance has this happened to anybody else?
