Unhappy with Small Implants and Want Larger Implants ASAP

I have recently had breast augmentation five weeks ago. I went from a b cup to a c cup with 250cc in the left breast and 275 cc in the right breast. It is a gel implant and is under the muscle. They look great besides the size.

I am extremely disappointed in how small they are and felt it was a little misleading when trying them on over your breast. I have a wide chest wall and still a large space between my breasts even with the implants.

I did this procedure to increase my self confidence and look more balanced with my body type. I had a healthy recovery and no complications.

I am so disappointed I'm ready to go back in and have larger ones (325 cc) put in as soon as possible. However, I am worried that after I have children they may change and I will need a third procedure. Therefore, I don't know if I should wait and be unhappy or risk it and do the second procedure asap while I'm young and healthy. (25 years old, 135 lbs, 5'6)
