Hi jasmine, I haven’t had my op, mines on the 3rd March but I will be exactly the same as you with nerves. I worry about everything haha but just remember why your doing it and how much it will be worth it in the end. I am a very small 34b and I am getting 375cc implants and I have no idea what size to expect either so don’t worry your not on your own with that one! Iv read a few posts on here about what to take to the op with you. Most girls take a V neck pillow, dressing gown, magazines, button up shirt/pyjamas or onesie, slippers and overnight essentials just in case you need to stay in for any reason. Hope this helps!xx
