Testing too early?

MG

Hi all, I’m 36 years old and have been TTC for a year. We had no issues conceiving our first 4 years ago but the second has been a challenge. We’ve been diagnosed w unexplained fertility. All tests come back normal, tubes are open, husbands semen sample was all normal. We’ve tried Chlomid, Fermara and even acupuncture with no results. Month by month I lose a little hope. I’m now 12 dpo and took a test with a BFN. I think in my mind I know I’m not pregnant, but am curious to know if any of you ladies tested around the same time only to get a BFP later in your cycle.
