after a miscarriage or d&c

How long did it take to get your period after you had a miscarriage and/or a d&c. I'm 4 weeks post d&c. My wondofo tests are negative, but I just got two positives FRER. I have no idea if it's leftover hormones or a new pregnancy. Just trying to see what others people experience wasafter theirs?!
