How long after miscarriage did you get your period?

I had an early miscarriage (6/7 weeks) , and had one day of very heavy bleeding and then a bit of discharge the next day, but not the length of a normal period. It's been over a month now, but still no period? Doctor said to wait at least a month before trying to would like to try again on my next ovulation ! How long has it taken others to have a normal period after early miscarriage ? Tia.
