Could it be natural for periods to be this far apart?

I’m 16 and already past the phase if irregular cycles since I’ve started, and have been for a while, but it seems like my periods are really far apart. After I got this app, I just set the time between cycles as 35 days, but my period is currently 5 days past that and I don’t feel like I’m going to start soon. I just want to make sure that nothings wrong, and see if this is just natural and healthy for certain people to have them this far apart. I also have minimum about 3 day periods then spotting for a couple days after if that means anything. It’s impossible for me to be pregnant too. 🤯
