13 weeks pregnant- no sex

I am so happy to be pregnant! Though I am upset with my husband....no sex (at all) since we conceived! He does have low desire which has been a problem before getting pregnant as we only had sex once a month since we got married. It used to be more often while we were dating but his drive changed. Honestly, I think that I’m losing attraction to him because of this. I love him but sex is really important to me and he doesn’t seem to care!
