Pregnancy symptoms??

Chelsea
I am currently going through a miscarriage, at least to my knowledge I think I am. And I'm experiencing pregnancy symptoms I had before the miscarriage like dizziness, nausea, sore breasts, fatigue, food aversion. All of these stopped once the miscarriage started 3 days ago yet they are coming back. The nausea more than before. Is this normal? Has anyone else experienced this?
