No more intimacy

Currently I am 14 almost 15 weeks pregnant with a baby boy. My fiancé and I had been speaking about having a baby for a while before it actually happened and I thought once I got pregnant everything would be great.... unfortunately things have been anything but. We haven’t really been intimate with each other anymore and i feel really self conscious about myself. I feel like us not having sex is a major factor. He barely touches or kisses me anymore and sometimes I do cry about it but of course only when I’m alone. I just want him to make me feel loved and make me feel how he used to before I got pregnant... and I’ve tried to explain it to him but it’s like nothing really gets through to him. I’m just depressed at the moment and I want my partner back in all ways.
