Had a d+c on 2/28. my dr. rec. that all his d+c pts. wait 2 cycles before trying again. is this necessary? healthy, no complications to procedure.

Probably not: It's probably not "necessary", but i also recommend waiting 2 cycles. This is not universally agreed-upon, and is somewhat a matter of opinion. After a d;c, the lining of the uterus is thin and might be less hospitable to a new embryo. And the area from the prior implantation may need time to heal as well. It just feels safer to wait.
