Sex in the first trimester?

Ladies!! I am almost out of the first trimester and I have only had sex once in the last 7 weeks. I feel so guilty and bad but I just don’t have a sex drive nor do I feel well enough. My husband is being very sweet about it and has not once made me feel bad or hinted that he wants anything. However, I still feel so bad. Any of you ladies battling low sex drive too!?
