i got told must have it on all the time, even now when changing i try get it back on quickly and i’m nearly 5 weeks post op. i know what you mean though i was the same at beginning, i would check but i don’t think five mins would hurt..maybe change sports bra it should be tight but not uncomfy as such. When i seen the nurse i thought mine was to loose thought it wasn’t holding them up enough but she said it was fine as long as fully supports xx
