Irregular periods: should I be worried if I’m trying to conceive ?

Hello. I need advice. My periods have been irregular for years now where they don’t come at all for months at a time, and then will for a month on a random day, continue for a week or two, then now come again for months. I’m getting closer to trying to conceive and I’m worried it will make things harder for me to. I went to a midwife and she told me it’s normal. Has anyone had this issue before getting pregnancy? Does his problem lower my chances of conceiving?
