Incomplete Miscarriage/Pregnancy

Amy
Hey Guys-
So we miscarried for the second time a little over a week ago.  I went to an appointment yesterday, and they said I still have a small amount of tissue.  My husband and I have already had sex again... We thought the miscarriage was complete, and really are ready to try again.  IF we were to be pregnant again already, would it be safe if there is still a SMALL amount of tissue that hasn't come out yet?
I really don't want a D&C to remove the tissue and am not a fan of taking the medicine to cause a miscarriage...I've passed the biggest part of this pregnancy already and can't bring myself to go through that pain again...
Thanks
