Could my implant have moved around if I accidentally slept on my side one week post op?

There's no need to worry. You don’t have to sleep on your back or sit up all night after breast augmentation surgery. You can sleep any way you want from the night of surgery on, including on your stomach or your side, if you are comfortable enough. You won’t pop or displace your implants by sleeping on them; they are extremely durable.

I am an advocate for back sleeping after a breast augmentation since sleeping on your side could affect the ultimate shape of the breast.  I also recommend wearing a supportive underwire bra after surgery again to support the desired shape of the breast.Having said that I do not think one night on your side will affect your results, but if you have concerns about how your breasts are healing you should follow up with your surgeon.Best of luck.

Thank you for your question. In general, I do not think that one night without support will likely affect your results.If you are concerned about your breasts I recommend seeing  your surgeon as he/she will always be your best resource for accurate diagnosis, advice, and/or meaningful reassurance.Best wishes.
