Can your cycles become more regular with pcos?

I was diagnosed with pcos at 13 and was on the pill until I was 16/17 so never really had the chance to experience irregular cycles, but came off of bc at 17 last year. I had a period in July and then one in January (6 month gap) and then one in late March early April (2 month gap). The gap seems to be getting shorter as I’m already having symptoms of my period coming (3 weeks later) and I was wondering if this was normal? I have very little experience with this and would just like some consolation that this is okay. Can your cycles become shorter on their own?
