It took me 6 weeks for my first period after the d & c. I had my d & c on the 11 Jan 08 and my first period came on the 18 Feb 08, so ruffly 6 wks But each person is different. Hope this gives you some idea.
It took 2wks for my hcg to come down, o'd a week later, then af 2wks after o. 5wks all together. I have seen some ladies with less time and some with more. I am sorry for your loss.
