Work being effected by pregnancy

Hi,

I’m new here! I’m 8wks 4days pregnant with my first and live in the uk. Like a lot of other people, I’m exhausted all the time and I have cramps and nausea on and off.

I’ve been asking work for a lot of slack recently- working from home and a couple of afternoons off sick and i’m worried they’ll think I’m taking the piss and judge me harshly for not working as hard as I usually do. I’m also aware that it’s really early days and I might need more time later down the line.

Any advice on how I can help put my bosses at ease and help my case? Has anyone else been in this position?
