Bfn at 10dpo am I out??

I’ve been feeling weird the past few days and today feel exhausted and nauseous. I tested Friday at 8dpo and got a bfn. Then tested today at 10dpo and saw a faint line as the test was processing that later faded away after the 3 minute testing window. I ovulated for the first time with this cycle after taking Letrozole. I’m starting to lose hope but will test again on Wednesday (13dpo). Do you think I’m out this cycle at this point?
