It is normal. Your period can return from 4-6 weeks after mc/D&C. The first period after my mc (I have had many) didn't give me any PMS. It just sort of snuck up on me.
I would say at this point it is worthy of a phone call to see what your doc says just to be on the safe side. He may advise you to wait another week or two, but remember he works for you and that's what he/she is there for. Take care.
i usually get mine 4 weeks. some 6 weeks. did you get checked to make sure it all came out?
Sorry I ment to say period MIA after miscarriage
