Can’t do maternity pics

My belly doesn’t look round at all i was skinny before I got pregnant but now it looks like a have a roll. I don’t know my belly doesn’t look like a normal pregnant lady I just look fat and when I tell people I’m pregnant they act all shocked. I’m 38 weeks and have been waiting to get maternity pics done to see if my belly will look pregnant but it hasn’t and it’s kinda crunch time. So what do I do get them done and waste money and see if I can try to take a good one or just not get them done at all and. Save money on outfit and props and a photographer
