Baby gonna come early?

I am SO SICK of people saying "she's not gonna stay in there til April 25th. Then when I ask why they say that they say "she's just not" ok maybe she won't but who asked you? It frustrates me because I want her to be full term atleast, no earlier and I just feel like they're jixing me. They're  basing it off the size of my stomach. I am not skinny..I had a gut before I got pregnant..so there was already bulge and bloat before my actual bump came. I'm sick of people saying it looks like twins. My baby is measuring right on track, she's not "weeks ahead" I haven't had any complications so far. I'm 29 weeks and have only gained 5lbs I'm not much bigger than most of the women on here who are due around the same time.
