Hello Hun’ I had a BA but I’m sure my pre surgery experience will be similar to yours!
I got to the hospital at about 8 saw my surgeon at about just gone 9! Where I was already prepped for surgery! (Gown, socks, the lovely knickers) he then asked me if I was okay and general chit chat! He took my before photos and then drew on the markings and took photos of that too! I was the second surgery that day so had to wait another hour and a half! Which was painful as I wanted if over and done with!!
I took with me: deodorant, tooth brush and tooth paste (just in case), baggy clothing as you are sensitive after surgery! Also my sports bras, I don’t know wether you need any after care support stuff! Also took my little bear with me for comfort which don’t underestimate it really helped lool! Also a bottle of water for the journey there and back! I think that’s everything? If you’re worried just message your PC!xx
