I am so sorry OP. I just told my husband last night that i feel my miscarriage kind of broke something inside me, so i imagine our 'wreck' state is normal and common.
My period came back normally after mine, so i can't speak to this, but what i can speak to, is feeling comfortable going into your OB. They are so amazing and supportive, and if you dont feel that way, then def find a new one. They can take so much of the wondering and anxiously waiting away with a quick appointment.
I wish you well OP.
