Everyone has a bump except me!

I see lots of ladies being 8 weeks pregnant or 12 weeks pregnant and they're rocking the bump. But me? Nah. I'm 13 weeks and 5 days and my belly looks smaller than it did before I got pregnant. My 5 weeks photo and my 12 week photo don't even look like bump selfies. Come on small human! (by the way this is my first baby)
