Bump or eating too much? I only feel fat!

I am 19 weeks 1 day today.

I wake up with a little hard baseball like bump below my navel and as the day goes by and I start eating, it starts becoming apparent I am carrying a baby! And then the same story. I am a FTM. Is this looking like a baby at all or am I going too easy on the calories and only overeating! Either way I can’t wait to look just pregnant and not fat! Lol

Please share your bumps!
