Should I see a doctor?

Here's my situation. We had a baby March 2017. I got my period back when he was about one. I breastfed until he was 18 months (September 2018). We've been trying to conceive since August 2018 and I know it's not long, but my periods have been all over the place so I'm worried about my fertility and that it can make it harder for us to conceive. I only had six periods since they came back and the cycles have been everything from 32 days to 57. I know it can take a while for your period to regulate after you've stopped breastfeeding, but for how long? I'm wondering if I should see a doctor about it or if I should give it more time to regulate?
