Told to wait a year ttc #2 because #1 was delivered by c-sect. Anyone else?

So I had my annual exam yesterday and Dr. said that I should wait a full year (ideally) before conceiving again because of the increased risk of pre-term labor (#1 was emergency C-section at 34weeks5) growth restriction and other complications.

Slightly annoyed as my regular periods have started and SO and I actively tried to conceive this month.

Has anyone else received this advice?
