Three Weeks and Counting - Colorado

I have been wanting breast implants for forever! I was very small in high school and wanted them back then but wanted to wait until after I had kids later on in life. I have three kids and I breast fed two of my three children (I tried to breastfeed for two months with my third) I got HUGE (DD) when I brestfed my second and that left me with smaller now saggy boobs, very small B. :( I knew I wanted one more child so I didn't think about implants until after I had my third. My third is now 5yrs old and I am ready. My surgery is scheduled for Oct. 12th. I went in for a consultation last year (to a PS referred by my friend who is a nurse and works for him in his surgery center and I LOVE him). I got a little scared and backed out. It it now a year later and I still want them done, I go in for another consultation, to ake sure we are still on the same track. (with same PS) on the 24th and my pre-op is right after, I am so NERVOUS!!!

I am 5' 2" 118lbs and can not figure out what size I should go with. I am going with silicone gel and my PS wants to go over because I am VERY athletic and do a lot of chest workouts pushup's, pull ups, fly's etc. I have done the rice test and originally I was thinking 250cc's then after trying on 300cc's I kind of like that look on me. I just do not want to go so big things like running, weight training etc will be awkward, but I don't want to think "I should have gone bigger." I will try and up load pics without rice sizers and with sometime later today.

I also have an automimune disease (hasimoto's thyroiditis) and I am scared of making it worse (it has been under control for a year and half now & levels have stayed the same for that long) I am also afraid of the implants "causing" another autoimune disease. I have read all the horror stories on the internet (bad idea LOL) I have also read that implants do not cause or are not associated with autoimune disesaes but then I see all the stories. I also wonder if breast implants can cause that, what about stunts, pacemakers, knee replacements etc they are all foregin objects some with silicone? I know I am WAY over analyzing this. I am huge worrier about EVERYTHING. I would just feel so awful is something bad happend and I did get sick. :( Really any type of surgery makes me scared, nervous and a bit crazy, I way over analyzied my tonsillectomy as well.

I am so thankful for this website and all the inforamtion/support it provides. My one big question is: Has anyone else had some kind of autoimmune disease and still got implants and are doing well?
