Nikilove,

I think it varies from person to person when i had my latest d&c done i was told i should wait until my next real period before trying again. There have been people that have gotten pregnant straight after a d&c have been fine.
As i don't know your circustances i can't say, as their could be some other things going on as to why your doc said to wait.
Thats just my opinion there are plenty of girls out there that have been through this and will also have more advice and support as well.
I would also ask your doc why he wants you to wait that long.
