After natural miscarriage symptoms?

Laura
I had a miscarriage on wed the 3rd at 6 weeks and it has been a week since then and I feel like crap everyday I'm overly tired and my stomach hurts all day long it gets worse after I eat. I feel like i am so hungry but then I eat and my stomach starts to hurt. I just feel crappy overall I feel fatigued and shaky and nauseous. I dont know if this is common but it's starting to concern me. Has anyone had anything like this? Please give me some insight so I know if this will pass or if I should see my doc. Thank you ladies
