Will a doctor be able to help?

These pass fews days I have been feeling very rough. I have been nauseated 24/7, I haven't been able to have go to the bathroom properly,(TMI: bowel movements have been nonexistent.) I have been having some cramping. Am I just being whiny and this is normal pregnancy life or can I get help with this issues by seeing my doctor? I'm going to call when they are open.
