Hi @beccs, @tayt2015…I had the same question, I agreed to have 350CC UHPs but decided a couple days before whether I should go a bit bigger with either 375-400. Spoke to the nurse when she rang to give me admission time and asked whether I could changed and she said it’s highly unlikely as they wont have ordered the other sizes implants. Decided to ask surgeon on the day (I had my op yesterday) and he said they could go bigger but as they haven’t got the implants they would have to cancel and reschedule my op so I decided against it after he reassured me they would look nice and big enough 🙂 where are you girls having your op and whose your surgeon?
