Hiya hun, I had a BA and nip lift too 16days ago and I don’t seem to have the double effect. Have a look at my pics if you want hun
I no girls who did have double bubble with a straight forward BA and it eased its way out by itself gradually as the boobies settled into place. Think it can be something to do with if they had to lower your creases in surgery, takes a while for the new creases to settle into place.
Try not to worry as yet, maybe wait till your 6 week appointment and bring it up then if it’s not gone. You coud jst ring the nurse to book in and let her have a look though if your concerned
