I don't know if I should go up a size in flanges here.

I have tiny nipples (TMI sorry), but the areola tissue is getting sucked into the tubing of the flange. My nipples are not touching the sides but my areola/breast tissue is, a lot.

I'm already in a size L. Should I order an XL size from Medela? Or do I need to go smaller so the breast tissue doesn't get yanked in there? I have a couple of M flanges i can try.
