Irregular cycle

I probably have the most irregular cycle known to man πŸ˜”. I'm trying to get pregnant but it's extremely hard when my period skips a month or two. Β  I have used <a href="">period tracker</a> and now glow but it rarely comes on the days predicated I range from 30 to 60 days inbetween periods. It's hard to tell when I'm ovulating. Β Is this affecting my chances of getting pregnant and how do I go about to fix it?
