Getting discouraged - 12dpo BFN

I am trying for my 4th and had no issues getting pregnant previously. This time is proving difficult and I know people have it much worse and I am so grateful for my 3 healthy children, but my heart knows there is one more missing!

I am 12dpo and a negative FRER. I had pressure/light cramping all day 10dpo and some 11dpo and felt extremely bloated - today feels normal with no symptoms. With my previous pregnancies I always had a faint line around 10/11dpo so I’m losing hope but no other signs AF is coming.

Has anybody gotten positive tests late in the game especially after having negative on a FR?
