Depressed about marriage

We were planning on getting married this December. I was going to the gym and trying to lose weight and gain my confidence back so that I can feel beautiful on my wedding day.. well now I’ll be pregnant and due two months before the wedding day 😭 so I’m probably going to b fat. Just the thought of it is making me want to cry. He wants to move the wedding up and I’m like 😭😭😭😭
