Low sex drive?

Lately I seem to have zero, absolutely no desire to have sex with my husband. I don't know what's wrong with me! I still love him and I'm attracted to him still. I just have no desire or passion when it comes to having sex. I can still get off by myself but when it comes to my husband, I'm just waiting for it to be over and acting like I'm enjoying it. What do I do?! 😭
