I feel pregnant...

I know this might sound crazy but I feel pregnant! Today is 9 DPO and I got a BFN again.. I have symptoms of nausea, tender breasts(feels swollen), and very very very very tired sleepy! This usually does not happen..! But after getting bfn today I feel like losing hope and keep thinking maybe it’s just this month my aAF is different... idk I’m just confused... has anyone gotten 9 DPO BFN and 10 or 11 or 12 BFP??
