when did you get your period after miscarriage

Me
We found out in December i had a missed miscarriage and I had a d&c two days later. Doc said you'll have period in 4 weeks then start ttc. Well it took 9 weeks to the day to get My period and one week later I'm still spotting. For anyone that's had a d&c how long did it take for you to get your Period and how long did it last? Any BFP out there right after ??
