Should I be concerned??

Kelley
Today I have felt worse than I have ever felt since being pregnant. I will be 12 weeks Tuesday. I have been so itchy, had a headache all day, and I just feel like I've been ran over by a truck. I typically have fatigue but this fatigue is nothing like I've had before. And while laying in bed, I realized I had this rash on my breast... I have been scratching all over but I don't recall scratching my breast. I'm gonna go to the doctor tomorrow if I don't feel better. Has anyone ever experienced this?
