You're a big A/medium B cupsize so I'd say go with the mediums. The smalls will be wayyy too small for you and the large may be too big, like super boob said it would be best, if you can, to get both the mediums and the large domes in one order that way you have them on hand and ready when you need them. I started with the mediums, I was a 32B when I started and I used the mediums for a couple months before needing the larges. It all depends on you on how fast you will swell inside the cups and need to move on in cupsizes, we all go at our own bodies pace. I have a child and breastfed so my skin stretch fairly easily, where as someone with the same cupsize starting out who has never had kids might not be able to move on from the M's for many many months, it just all depends. Hope this helps and good luck!
