B Cup+ 440cc Silicone Modplus= ? (23yr Old, 5'5", 138lbs) - US

I'm currently a 34B not sure what cup size I will ultimately be but I'm scheduled to have 440cc silicone implants, under the muscle with "underboob" incision.
I'm super indecisive about the size, I NEVER thought I would want anything more than a small D..but when we were putting the sizers in, I kept asking for the next size up. Knowing that they will look slightly smaller in my body, I think 440cc will look nice. Hard to tell though, just looking with a shirt on is one thing..but I wanna know what they will look like naked.

A little nervous about the pain/recovery.. this will be my first surgery. It's on a Tuesday and I have to work that Saturday so I'm hoping to be up and functioning without too much pain then.

Very excited/nervous!! I just wish I knew what they were going to look like!!

I'm going in tomorrow for the 3rd time to look at sizers. I'm so nervous, I don't want to wish I went bigger like I see sooo many people say.. but I don't want to go too big and end up hating them. I think 440cc will look good, that is the biggest size implant they would allow after measuring the width of my natural breasts. Tomorrow I'm going to take pictures with the sizers in and post them.
I bought some wireless bras yesterday to wear during recovery and got my prescriptions filled.
I'm so anxious, I cant focus on anything else right now, ahhh!

I went in today and saw the pre-op coordinator again, she handles the sizing and goes over the pre-op instructions. My mom came with me this time because I wanted her to see I wasn't going with a HUGE implant which I think is what she was imagining. She isn't supportive of me getting a BA and I live with her right now so I've been hearing on a daily basis about how much I will regret getting implants -_- She and all the women in our family, except me, are naturally large chested (mostly all DD cups). I think she feels better about it now after asking a few questions and looking at the sizers.
Funny thing is, I almost thought the 440cc looked too small today lol boob greed already?? But I'm already getting the largest implant for my natural breast width so I can't really go bigger without having them go off to the sides. Also my mom took pictures on her phone, I didn't take photos last time. I looked at them when I got home tonight, the 440cc looks like plenty in the photo :) I only have one pic on my phone to upload, I'll get the rest from my moms phone tomorrow.
