Constant late periods

Hey girls

Has anyone always experienced late periods? Mine have never ever been regular. I was told when I was 16 I had PCOS but later told in my early twenties that I do not have this but do have cysts on my ovaries.

I’m fairly certain that I can’t conceive. My partner and I don’t use contraception if any kind and we have never had any scares. Can someone please let me know if they experience late periods, no scares when there probably should be scares, and intense depression prior to periods finally starting?

I’d love to have children of my own some day but I have this deep rooted feeling that I’m unable to.
