No baby belly

Asia
I'm 33+4 weeks and some days I have a belly and sometimes my belly is saying find me! It was so embarrassing for my maternity pictures I had to fake a belly by pushing my back out! 😑 I just don't know if I'm over reacting or its normal!! Am I the only one?? Please tell me I'm not!! 
No belly on this day 
But I'm huge this day! 
 
Pictures were taken a few days apart!
