Pregnancy relationship drama?

Before getting pregnant my boyfriend and I got along perfect. We were so happy together and I was so in love. He is great, very loving and treats me so well and handles my crazy mood swings so well. But since getting pregnant (I am now 15 weeks) that spark has faded. Some days are better than others, but I have lost most of my attraction towards him, I don’t want to have sex and sometimes I don’t even want to look at him. Everything he does bothers me. I have read various things online and just wondering if this has happened to other mamas out there, I’m hoping it truly is the hormones and it will pass, it is kind of starting to stress me out a little bit.
