i cant decide on the size of implants

My doctor's office is recommending 350cc but i feel like going under 300cc as i just want to be a little fuller and not super big.  Im 39, never had children, 5'2", about 114lbs. Currently 34A and just want to be a full B or a very small C.  I was told that a lot of factors affect final outcome and i cannot compare other women's breasts to what mine will look like.  Im feeling the pressure as surgery is 2 weeks away. Ive also been reading the answers on breastfeeding. I do still hope to have at least one child in the next few years, dont know exactly when but i was hoping that feeding will not make breasts sag but as read in the forum, it will all depend on each individual and there is no way to really tell what the effects will be.  

thanks

I find the best way to have patients participate in the decision about implant size is to place different sized implants beneath a sports bra and have the patient judge size after wearing a top over the bra.  While this is not exact, it is close enough to settle on size with very few complaints about inappropriate sizing.  The hormones of pregnancy can certainly affect breast size after augmentation, but it is impossible to predict the outcome that pregnancy will produce.
