Sex drive & pregnant

I’m 16 w pregnant and literally have nooo sex Drive. I’m taking labetalol so im not sure if that affects it. But I haven’t had a sex drive In weeks and it’s really annoying. I feel bad for my SO because we never do it and I feel like he deserves it but I just cant make my self enjoy it which is usually for me. I feel horrible. Has anybody else been like this? And what’s some ways I can increase my sex drive while being pregnant??
