Should I be concerned ?

I posted last night that my man has lost all sexual desire for me , well he tried to last night and it took him ages get hard , he kept playing with me to make it go back hard and I could just tell he wasn't enjoying it with me which of course was a huge turn off for me, and made me completely dry up to be honest , I let him finesh off he sorta wanked a bit and put it in me and I just felt numb I just knew he just didn't really want sex with me ! I don't really know what to do ? I'm going quit trying for sure I was so upset afterwards , this has been going on since before I got pregnant we actually decided to quit ttc it was taking its toll on us both a couple of misscarriage down the ttc road , I actually conceived within 10 days of a chemical pregnancy we totally wernt expecting it as we avoided sex near my supposed fertile time and I'm 14 weeks now , it's kinda been like this for a while , I'm wondering if to offer him a break ? I just don't know what else to try ? its sad but we are both unhappy at the moment , I'm unhappy due to the loss of care from him I feel lonely and like he doesn't give a shit , he doesn't find me attractive anymore I love this man with all my heart and I'm at a total stand still I really don't know what to do ?
