I think you should go to the doctor, if you are checked out and don't need any other help it's sometimes nice to have someone to talk to, that's not family/friend. Also the emotional reactions can be delayed and doctors are trained to help you with these as well.
Sorry to hear about what happened, sending strong feelings your way!
I'm sorry to hear of what you're going through.
You should definitely see a doctor. Even if you just go to your local hospital and see the OB on call. They may want to do blood tests to confirm that your hormones are decreasing at the proper levels.
I agree that you should see a doctor. It's also important if you have miscarried that they make sure the miscarriage is complete. If there's anything left in there that shouldn't be it could cause a serious infection. I hope everything's okay, and keep us posted!
