Feeling self conscious

I’m 11+2 today on my second pregnancy, (miscarried at 14 weeks with my first), and already feeling so huge. My stomach is round, firm, and I’m always short of breath. I actually lost weight since becoming pregnant and was not expecting to look this far along so soon. I’m feeling really self conscious because I know you’re not supposed to show till 12 weeks or farther. Can anyone else relate? I guess it also doesn’t help that I haven’t announced my pregnancy yet.

Sorry I’m not wearing a bra haha
