Postpartum sex

My poor husband. I lost my sex drive completely when I got pregnant last January. The last time we had sex was the beginning of February 2019. My daughter is now almost 5 months and we still haven’t had sex. He says it’s okay because I apologized but I still just feel horrible. Lately I’ve been wanting to try to have sex again but we co sleep so I don’t know when to even try or how to bring it up. Also has this happened to anyone else? I feel like the only couples who don’t have sex for a year get divorced or are separated or don’t love each other and that’s not the case with us at all I just had a horrible pregnancy and I’ve been scared postpartum and since it’s been so long idk how to address it. I used to have the craziest sex drive I just want that back 😫
