My friend had a BA and went on holiday 3 weeks post op :-0 defo too much of a risk if you ask me ha but she was lucky!
I think 10 weeks would be fine 🙂
You will have a 6 week check up and at that stage everything should have heeled and be ok to wear bras etc
You have to take care with your scars when sun bathing, either cover them up or use factor 50!
Hopes this helps, as you mentioned if you speak to your PC/ nurse, they can give you the best advice xx
