Two Weeks Of Healing !!!

Tasia <3
So I found out maybe a week ago when I was just hiting my 8 week Mark in pregnancy that my baby didn't have a heart beat wanted to have a D&C to just move things on. But ended passing the fetus 3/10/15 still went to my D&C appt 3/11/15 and turned out I still had a little tissue left in me stop bleeding that same day and I'm feeling fine today Dr says don't have sex until we see her in two weeks but I'm getting anxious I'm really ready to try again I heard you are fertile after a bby/loss is this true??? Has anybody else just went for it without waiting the full two weeks and had a healthy pregnancy? Also won't my cervix be closed in two weeks . You would think it would be a little hard to try again.
