Irregular periods & pregnancy

When I got pregnant with my first child it took 11 months. I wasn’t tracking ovulation and we weren’t “trying” it was kind of just if it happens it happens. My periods were also relatively regular. I’m hoping to start actually trying for another baby towards the end of this year, but I’m starting to wonder/get worried about if it’s going to be hard to get pregnant quickly with my super irregular periods. My cycle now ranges from 27days to 52days. I’m not even sure when or if I’ve ovulated. Do you guys have any tips or advice?
