My sex drive disappeared 😭

Le

Where did it go? I’m 32 weeks now and as of about 29 or 30 weeks I haven’t had a libido. It’s gone! I don’t like it cause I love my partner and love to love on him and the whole rest of my pregnancy he couldn’t keep me off of him and now we maybe have sex once a week if that. And when we do I lose my libido right in the middle of it. And he knows it isn’t him and he’s really sweet about it and caring and he doesn’t get angry or upset with me. He’s understanding. It’s like my mind wants him but my body doesn’t. Is this normal?
