Ttc after a d & c

Hi. I had a d and c two weeks ago due to a blighted ovum. I'm wondering how long you were told to wait before ttc again. We are very eager to try again. My dr said to wait a full cycle but everything I'm reading online says that's just so they have a better idea of your due date. Is there any medical reason to need to wait a full cycle? Also, when did you ovulate after the d and c? Did the day of surgery count as day one of your cycle? Thanks!
