Maternity pics

So before i got pregnant I gained weight due to the thyroid issues and medication. I'm not extremely overweight but I'm not where I used to be or comfortable with myself. I had my baby shower about two weeks ago and all I see in pics is my double chin lol. I'm 5'2-5'3 currently weighing 199.  I've gained 16 pounds this entire pregnancy. This Saturday I'll be 38 weeks and I've put off doing maternity pics because I'm so unhappy with my weight. I really want to take pics but I feel very insecure. On the other hand if I don't take the pictures I feel like I might regret it. Any advice?
