too big??

cherish
Is there a such thing as being too big too fast when pregnant? I'm 11 weeks and naturally a small person, 5'2 120lbs. I swear my stomach is HUGE, and others have confirmed this so it's not all in my head lol. Idk if it's just bloating or what but I'm extremely uncomfortable to where I even feel short of breath. Has anyone else felt like this? Am I just overreacting?
