Myo inositol or Premama Fertility without PCOS

So I have always had very irregular cycles, and was hoping I would find they had balanced out with age now that I'm off birth control, but no such luck. I've read good things about myo inositol, especially for those with PCOS. The thing is, I haven't been diagnosed with PCOS. I just have really long, irregular cycles but I don't really know why. Anyone without PCOS have a good experience with taking this?
