35 day cycles

Anyone have long cycles ?? I just used a website to figure out how long my average cycles are and it came out to 35 days... I'm also ttc. Also has anyone gotten an early bfp with long cycles if so what DPO or cycle day ? I also had some spotting/bleeding that only lasted 1 1/2 days. Took 3-4 tests all negative but might have been way too early
