Maternity photos

My cousin is getting into photography and she wants to.do maternity photos for me. I want to do them too so bad but at the same time I hate my body and feel like I will hate the pictures. It isnt even the belly its that my boobs are too big, I feel.like my arms will look fat, i have big legs and I hate them, and Im scared of my bra making it look like I have back rolls because I cant find one that looks good with my boobs getting bigger. Everyone always says oh youre just pregnant but I hate those little things and I know she will.just tell me they are beautiful and so will my family but I really feel like I will hate it. It makes me not want to do it but I dont want to regret not doing it either. I would wear something lose and cute but then I look way bigger than I am because of my boobs. My boobs are bigger than my belly and its depressing.
