question about my implant replacement

I was diagnosed with triple positive breast cancer in my right breast in November 2014. It was borderline stage 1/stage 2. I had a mastectomy of my right breast, 15 months of chemo, and reconstruction surgery (2016 - 2017). During reconstruction I opted to have my left breast removed so that I would not sit around worrying about getting breast cancer in it. My plastic surgeon used textured implants. It turned out that I went from a B cup to a D cup, which I was extremely happy with. I had always wanted larger breasts, but would not put out the money for a look I could achieve with an add a cup bra. There were small issues in that the right one was much rounder than the left one due to skin loss and it having to be stretched. Also, on the left side I have an indention above the breast that my plastic surgeon said I needed fat grafting to fix. I couldn't have it because my insurance would not pay for it. However, it was only noticeable when I flexed while exercising. Also, the left breast was slightly smaller than my right breast. I know that breasts are sisters, not twins, but mine were more like 2nd cousins. However, I was so thankful to have gotten them back and to have the added bonus of larger breasts that I didn't let these small imperfections bother me. My plastic surgeon retired and when I went see my new one, he told me that research in the past year had shown that the implants I had could cause lymphoma. I had received a letter from the company that made the implants about this issue about 1.5 years ago. I talked to my oncologist about it at the time and the general feeling at the time was that it was false information and the company was taking the implants off the market to avoid lawsuits. However, my plastic surgeon told me that was true at the time, but further research had confirmed the link to lymphoma. He suggested replacing them with smooth, round implants, which would give me the rounded look I wanted to begin with. My original plastic surgeon never asked me what I wanted, but that is a different story for another time. He asked me about size and I told him that I wanted to be the same size and definitely not any smaller. He said he would use the same volume on the implants except for a slightly larger one on the left so that my breasts would be the same size. I had surgery this past Wednesday. Once I got over the anesthesia and strong pain meds, I gave them a good look. They are so pretty, look the same size, and are round and full at the top like I wanted. I no longer have the indention above the left breast. However, I am no longer a D cup. They looked a little smaller to me than the ones I had, but I figured I was just imagining things. It was bothering me so badly that the next day I decided that I would try on one of my D cup bras (without underwire) for just a few seconds to be sure. And sure enough, I don't fill out the cups anymore. I am probably more like a C cup. He used the same volume implants he said he would use, because I have the paperwork, so I don't know what happened. I know this is a 1st world problem, but I have been so tearful and upset about this. I know it is silly, but I cannot stop crying about it. I tried to talk to my best friend about it, but she told me I should just be happy to be alive, which made me cry even more. I have no one to talk to about this issue except on this forum, which I just found. I know some of it is probably after surgery depression, but I am so disappointed, especially when he indicated that I would be the same size. I see him on Monday to get my stitches out on May 24th. Should I talk to him about this? Should I tell him I am disappointed in the size? If so, I don't know if I can do it without crying. I don't know why this has upset me so much, except that I have been so happy with the D cups, that I feel a loss. Before I went home he mentioned something about having difficulties on the right side because of it being "so tight " but I was so out of it from anesthesia, that I don't remember exactly what he was talking about. Does anyone know why I am a smaller cup size with the same size implants as the previous ones? Do different implant styles behave differently? I am wondering if what he meant by "so tight" will mean that I can't get larger implants. If that is the reason, then I am fine with it. However, If he offers to replace them with larger implants, I don't know if I want to go through surgery again but I am afraid I will regret it if I don't. Please don't judge me on this, but If you can answer my questions or have any encouraging advice, I would appreciate it.
