1. Don't test super early.
AND
2. Throw away the BFN test and don't dig it out to re-examine it.
I started testing at 8DPO with a FRER and it was negative. I saved the test and looked at it a couple of hours later and I could see a faint line. I thought it was the start of a BFP so I got my hopes up and tested the next day...and the next...and the next. Nothing but BFNs. I've been in a funk since last Thursday. Ultimately, I blew about $40 on pg tests by the time AF started today. This cycle, I'm determined not to test until 12 - 13 DPO at least. BFNs are so hard to look at...expecially when you're expecting the opposite.
