Anovulatory cycles?

ca

So my periods are irregular, it never usually gets to the point where I miss an entire month, but roughly they very from 30 cycle days through 40 or 42. I haven’t gotten checked out but I plan to see a gynecologist next month to see what’s going on. I’ve been irregular my whole life, I have a good diet, I’m a very healthy person, and I’m not stressed out or anything. I’ve read it could be PCOS, but I really dont have any of the other symptoms for that. I also read it could be something called anovulatory cycles, which basically means your periods are too far apart to ovulate if I’m reading it right. I’m really concerned because I desperately want a family some day and so does my partner. I know I need to go on with the doctors appointment to know for sure what could be causing it, but does anyone have any advice or thoughts to put my mind to rest? Or have any of you had any similar experiences?
