Time of month ( TOM )

I’m sure someone here as been in the situation I am currently in I could use some insight. I got my first period at 12 fast forward to today I am 22 and I’ve ALWAYYYSSSSS been irregular. In a 10 year span I’ve only been on time about 4 times which isn’t enough you know. What do you do when you want to start soon trying for a first child? How can I track if I’m always late? I’m currently 33 days late. It’s becoming frustrating sometimes because we do want to start soon.
