My last FS said that you are more likely to get a BFP after surgery? is this true for a D&C?
It can happen but I don't think it happens as much as people say. I kinda put a lot of hope in this theory but as you know, it didn't work that way for us.

As for the scaring - I think some people are more prone to it than others, part of it is luck, and a big part is the skill of the surgeon perfroming the procedure...
