How soon after pregnancy can implants be affected?

it is highly unlikely that your pregnancy affected your implants. Since you're only pregnant for three weeks the changes in pregnancy during that short period time would not cause rupture of your implants. I'm not sure how long your implants have been in place, but implants overtime are prone to rupture. I recommend seeing a board- certified plastic  surgeon to evaluate you properly and safely.

From your description, it is unlikely that your pregnancy had anything to do with your ruptured breast implant. Normally there will be little changes to the breasts this early in the pregnancy. The rupture however should be evaluated by a plastic surgeon in person to better determine the next, appropriate intervention.You should see a board certified plastic surgeon in your area to get a formal opinion through an in-person consultation.Best of luck,

Dear LKR2015:I am so sorry to hear of your loss. At three weeks of pregnancy, there is little to no change in your native breast tissue. It is also uncommon to have two leaky implants present simultaneously. It is my opinion that your pregnancy most likely did not effect your implants. I would suggest you see your personal PS as soon as you can to have an exam and evaluation. Good luck and be well.
