Trying again after miscarriage..

I had a miscarriage in early November at a little over 8 weeks. We had been ttc for 7 months when we found out that I was pregnant. We were so excited and grateful, then a month goes by and I had faint spotting I mean barely anything but i went to the OB the next morning for a ultrasound and unfortunately my baby no longer had a heart beat. This has been such a heart wrenching experience for me and my husband. I know that many other woman got through this same pain. My question is I have been cleared to start trying again and I have been for a couple weeks but I still haven’t had my period. How long has it taken for y’all to get y’all’s periods back?
