Month After Miscarriage

My miscarriage began November 11th and continued to November 19th. I have not had bleeding since the 19tg and Glow says by period should begin around the 14th of December (since no adjustments are made in the calendar for miscarriages) I am having heavy cramping, which is very unusual for me. Along with what seems to be VERY elevated PMS symptoms (moodiness, fatigue, cramps, cravings and nausea). I think since I had the miscarriage only a month ago, I probably did not ovulate like normal. Today, I would be approximately 7 DPO if I follow the Glow calendar. But all these symptoms are very weird to me. Has anyone else had issues like this the month after a miscarriage? Any advice or personal accounts would be greatly appreciated! Thank you! ?
