Insecure

Lauren
I'm a FTM so all of this is so new for me. I'm short; 5 foot 1 and usually around 115-120lbs. I'm normally really active but when I found out I'm pregnant I was so tired and sick all the time so I never made it to the gym. Haven't worked out in like 2 months :( now I'm back at work (I'm a teacher) and I'm so tired when I get home it's hard to feel motivated to work out. 
Well the bottom line is I feel so insecure about my growing belly (because I feel like it's just fat-I'm 18 weeks 3 days). And we took staff pictures for our badges and I feel like my face looks so fat. I just feel so insecure. It's hard :(
