I know I am only 2nd Tri but I thought some ladies in here might be able to help me. Over past 2 weeks i have been really irritable and depressed to the point where I am becoming easily upset over everything and not functuning in my job as well as I usually do. I am really tired, get easily short of breath and have no appetitie (have actually lost 2 pounds over past 2 weeks) and am only 9st 5 (5ft 4in) anyway. Is it just usual preg niggles or something more??
