Ttc after a d & c

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 ttc again. My dr said to wit a full cycle but everything I'm reading online says that's just so they can date the oregnancy easier. Is there any medical reasons for needing to wait a full cycle? Also, when did you ovulate again after the d and c? Did the day of surgery count as day one of your cycle? Thanks!
