Unders can often take a lot longer to settle and drop than overs as they are being held in by your chest muscles, ring your nurse and ask about maybe trying a breast band, not very comfy apparently but by all accounts if it helps your muscles relax and your implants drop then its only a good thing. Also ask about gentle massaging, this can also encourage the muscle to relax and allow the implants to start to settle. Hang on in the chick, xxx
