Are large areolas a problem?

Ji

I'm pregnant with my second baby. I tried really hard to breastfeed with my first, but she was a preemie and had to start being supplemented with formula in the NICU. I never was able to build up my supply and pumping milk hurt like hell. I had a medela pump and saw lactation consultations a lot, but my baby needed to gain weight and I ended up having to give up breastfeeding a month or two postpartum. I know that my whole problem was not pumping related, but it might help if I can figure it out this time. I have large areolas, could that be an issue? I tried different shield sizes, and a lactation consultant told me which one should be best, but should I try a different pump? Or is it something else?
