Want to try again...but scared too.

I started the process of miscarriage on Friday 12 Jan. I am having a D&C; done today as I have not passed all tissues and two doses of cytotec have not helped. My husband has been super understanding and says we will just keep trying and I do want to try again, I just don’t know how long to wait the doctor said two weeks after the D&C; and after my HcG is back to under 5. I know that there is a chance of infection and all the other negative possibilities from a D&C; I just want to be close to my husband again. HELP!
