Advice?? UK ladies

Hey ladies, I’m currently 16 weeks pregnant and haven’t been having an easy pregnancy from the get go! I had hypermesis for 4 weeks and now I’ve been hit with extreme exhaustion. I can barely manage 4 hours a day before I have to go and have a deep sleep. I’m still being sick every morning and sometimes occasionally throughout the day. All my bloods have been tested and I’m not anemic. I have a job that I work 40 ours a week and I’m really really struggling, I work one day and then I basically have the rest of the week off because that one day has exhausted me. I’m not sure what to do as I still need to be bringing in money but I can’t possibly go to work everyday which my boss has a really issue over. Due to this I get major anxiety at the thought of work because when I’m there I have to go home ill and my work hate it. Is there anyway I can not have to work but still get paid?? I’m leaving my job when baby is due anyway. Thanks
