Am I out?

Today I’m 14 DPO and a BFN. Been TTC for over a year, this was my first medicated cycle. This cycle I took 5 mg of letrozole, did an ovidrel trigger shot (11/24) then took estrogen and progesterone. Feeling so defeated today.

Anyone get a BFN at 14 DPO then go on to get a BFP a few days later?
