My belly

Oh god, I really, really miss my belly. I know I get a baby out of this deal, but I am so scared of extra skin and stretch marks and just never looking like I did before. What prompted this panic? I was looking at pictures I took when I thought I looked pregnant and was sure EVERYONE would notice. I also miss being able to lay on said belly and have sex (in more than one position and without feeling like I may die from exertion--that is enough motivation for me to never be fat). I am so over being pregnant. I just want my body back.
