NEED HELP!!

Since i been pregnant, i have not had an orgasm during sex and i am only 13 weeks. Am I doing something wrong, is it me? Is there new things I could try to get me closer to orgasm during sex? Because right now i feel like it is me and that this is how its going to be the rest of the pregnancy. I feel like he isn't attracted to me anymore. Fricking pregnancy hormones has me all of the place about this.
