Pregnant and Implants May Have Ruptured

Since you are in your third trimester, this makes it very hard to know what is going on with the implants since you undoubtedly have alot more breast tissue now then before your pregnancy.  This may actually just be a consequence of the breasts getting larger and there being more room now for the implants to move a little.  The only way to know is to find a board certified plastic surgeon in your area.  You could also call your previous surgeon and see if they have any recommendations for your area.

If these are saline, essentially the leaking saline will be absorbed by your body. The primary concern will be contraction of the breast. Replacement tends to be a simpler procedure with less pain than the initial procedure. IF you are intent on using the umbilical approach then I would contact your original surgeon. Depending on their technique, these could potentially be replaced under local. The physician may have concerns about operating on a lactating breast and this should be discussed with them.
