Ahh how did it go? 
Mr Singh is right, start wearing it when the tape comes off.
Do you not have another padded sports bra that you can wear? If not then I advise you to buy a couple as soon as possible because it’s not a good idea to keep wearing the same surgery bra as the risk of infection is considerably higher. I know it’s weird but you’ll only have to wear it until you can find a suitable alternative which shouldn’t be too difficult.
For now though, wear the Macom so at least you have some kind of support…you don’t want one or both of your implants bottoming out…trust me! xx
