Flu Symptoms During Pregnancy

What are they? I don't know if I'm just being paranoid, or if I should call my doc in the morning. I'm 16w 3d, and I've been crazy exhausted, had chills and felt feverish off and on, my appetite is in the trash (and even when its not my stomach is picky on what sounds okay), stuffed nose, and I've been having leg pains and occasional abdominal cramps. Problem is, the exhaustion, congestion, weird opinion on food, and even the abdominal cramps were already present before the rest started, because they were normal pregnancy stuff.

Thoughts?
