BFP in 38 day cycle

When did you get your BFP with your 38 or so cycle?? Mine typically range 35-38 and this cycle the app is saying I’m 1 day late (14DPO) and I’m still getting BFN but possibly a VVFL on a FRER yesterday. So I’m waiting 2 days, until tomorrow to test to see if there’s a darker line. After those results I think ill stop if it’s negative. I’ve used a ton of tests. I will go back to testing weekly until my period comes like I usually do. I know I could just not be pregnant but I missed my first pregnancy because I stopped testing and that was 5 years ago before all the apps and I can’t remember the details lol I know I had mistaken “implantation” or early pregnancy spotting as my period and then thought my cycle was just a longer one. Sometimes I skip a month. This time I had a spot of blood around 9DPO so I’ve been thinking this is it plus I feel off.
