Hi There, I Started HCG Shots Under My Dr's Care

Hi there, I started HCG shots under my dr's care Saturday a.m. It was early in the morning to mimic the time I would get up during the week then I went back to bed to sleep in. I woke up with what seemed to be seasonal allergy onset, congestion and itchy throat. Once I was up and around I experienced Chest Tightness. The same thing happened to me on Sunday. I didn't do a shot on Monday a.m. and no symptoms. Can it be the HCG?
