Fatigue

Omg fatigue is killing me!!! I barely have any other symptoms! (Occasional nausea and huge boobs but thats it!) but this exhaustion I cant even put into words. I basically barely make it through work and the drive home. Then plop on couch. I feel bad too cuz my hubby just called snd asked if i wanna go out to eat but thethought  of it makes me even more tired:-/ i hope this lets up soon!!! Im 7w3d. Anyone else have overwhelming fatigue??
