26 year old, no kids, 5'4" 125lbs small A to small C

Hello! First of all, thank you to all of the wonderful and brave people who have shared their stories, feelings and photos on RealSelf! It has given me the courage to do that same.
I am 26 years old, no kids yet (someday)! I am 5'4" and weigh around 125 (depending on the day, haha). I am an A cup, on the smaller side of the A I'd say. I waited and waited...and waited for my boobs to come in, and turns out, I'm still waiting lol. I struggled with the decision to get a breast augmentation for a long time, going back and forth trying to be content with my body and thankful to be healthy! I would feel guilty sometimes for even wanting to alter my body this way, and often felt guilty. But I am now in a place of confidence about getting implants and truly feel that there is nothing to feel guilty about. I have a lot of confidence issues as a result of my tiny boobs and also have a hard time feeling sexy and womanly. Maybe because my small boobs are coupled with a very young looking face. I'm tired of people thinking I am in my teens and must still be in high school. No, I am not. I am 26 and have been married for 4 1/2 years! Ultimately I am doing this for me, but I am also terrified of what my family might think, and it's not the sort of thing you can hide! It's going to be unavoidable, but I guess that's ok. I know my Mom is very supportive and even excited for me. I just don't want to be a bad role model to my young nieces, sending a message like, "you have to look a certain way to be beautiful or feel good about yourself", because that is NOT what I think! I just know that for me, I would feel more confident and more like a woman if I had larger breasts. But I will be more than happy to talk to them about it if they ever wanted to. My husband has been so supportive of whatever I decide to do, boobs or no boobs, he loves me either way, which is more than a lot of women can say.
So, a little bit about me and what I am hoping for. I have a small frame and am fairly active, except in the winter when I am in hibernation, ha! I am hoping to be a full B or a small C. I am just so worried about going too big, and I think anything bigger might look very out of place. Although I have followed a few women on here who went 300 cc or larger and it looked amazing! So I guess I will have to ask the surgeon about this...and a million other questionsI have. I am thinking under the muscle and silicone (not sure round or teardrop). The most important thing to me is that my breasts looks natural. I am also afraid of having a huge gap.
I have 2 consultations scheduled in early April and will update on how they go and what the surgeons suggest. If there is anyone on here who is starting their journey like me, I would love to share our experiences and support each other! And if there is anyone who has "been there, done that", I would love to hear from you, too! Any advice, tips, suggestions, anything is welcome here! I am just hoping to find some support here :) Thanks everyone!
Here are a few pre-op photos, and I'll post some wish boobs soon!

26 Y/o 5'4" 125lbs, No Kids and No Boobs! - My name is Holly and I am 26 years old. My husband and I have been married for 4 1/2 years and have no little ones yet! I am currently in nursing school with the hopes of coming out the other side with my RN! Still about a year out from that, but one day at a time!
Anyways, I wrote a whole nice long story on my profile if you're interested in my life haha but I'll keep it short here...my boobs stopped growing when they reached an A cup and it's always bothered me, so here I am! And a quick thank you to everyone who has been brave enough to share. You have all helped me so much that I feel I have to post my own journey now to help someone else out.
So, my stats and the plans!

BWD 12.5 (I think)
Surgery date: May 31st!
Ahhh!! Finally my consultation happened! It was great and the doctor is fantastic. His name is Dr. Koenig and he's been doing this for 22 years. I feel 100% on board with choosing him...so I booked my surgery!! It's not until May 31st. Yesterday when I booked it, I was flyin high and feeling AWESOME. And oh man...today I feel 100% GUILTY. All the sudden I feel like the most selfish person in the world and also a little bit like, what if I miss my small boobs?? I'm going to look different! And thats what I thought I wanted for...well, forever haha since my boobs decided they were done growing! But now I feel like, do I really need to drop $8k on something for myself?? Is that ok?? And all of the sudden I'm so concerned and worried about what other people will think of me (especially my grandma!! she's NOT going to like it). But my husband is still behind me going through with it all the way. He has been talking me off the ledge today ha. I guess it's going to be a roller coaster from now till surgery day. I mean, it is almost 2 months away, that's a lot of time to think, rethink and overthink something. I know there will be other days where I know I am doing the right thing for me. I just seem to be struggling with guilt at the moment :/ I'm a clearance, find a good deal, Goodwill type person. So deciding to spend this much on myself is really uncomfortable for me. I guess now that it's real and I have a date and paid a $750 deposit, I have that "I might throw up" feeling in my stomach. So, anyways, don't know if anyone else felt or feels this way, but that's how I'm feeling today!

Guys...I am having serious doubts about going through with this BA. I have also been reading a lot of explant reviews and people who are unhappy with them after years. That's the thing. Lots of people post throughout the first year, but you don't get good insight into what it's like having the implants in for like, 10+ years. These things stay with you! And that's definitely something that shouldn't be downplayed. I've also read a lot of stories where people developed problems with their implants after around 5 years.
I probably shouldn't be focusing on the horror stories, but I also think it would be unwise to totally ignore them. Complications do happen and that fact needs some serious consideration.
Another thing that is giving me pause for thought is kids. I know that within 2-3 years my husband and I will want to start trying to get pregnant. On one hand I am feeling like I am young and have the opportunity to do this now! And on the other I'm thinking that after I have kids, my boobs are going to change and probably sag with or without implants. So, is it worth the 2-3 years to have and enjoy the implants now? The alternative is waiting for who knows?? Ten years possibly?? Yikes, that's too far to even guess at what my life will be like at that point. So, ultimately it feels like a now or never deal which makes me feel anxious and unsure. I already put down a $750 deposit, but I still have a small window of time in which I can get my money back if I cancel my surgery.
If there's anyone out there who can attest to long term implants and all the maintenance that goes along with it, please share you thoughts and experiences with me!! I'm desperate to hear from someone who has been there done that. And if there's anyone out there who wants to share any advice or words of wisdom, I'm all ears!! I feel like I need some perspective.
