Flange size

Jessica

So I was wondering if anyone could help me with sizing. I pumped with baby #2 and used a medela with the 30mm flange.

I got a new breast pump for this baby, Ameda Mya, and have been using the 24mm flange. That is what it came with. I ordered the 30 mm ones and just got them. They look way too big and don’t seem to be the same size as my medela 30 mm flanges. I can post pics in the comments if anyone can help me determine if they are the right size.
