Crappy Co-workers

Cassie
I just need to rant a little 😑 I work as a CNA in a smaller facility with a bunch of women who have no idea what it's like to be pregnant. At 34 weeks I had an extreme gallbladder attack which added more appts. And now a surgery after the birth of my son. Because my gallbladder is bad I have been VERY ill. I also have had HG through my WHOLE pregnancy. When I had to call in (actually had to have my fiancé call) I was in the hospital in horrible pain and my boss told him after I was "done" I needed to find a replacement for my shift!!!!! What!?! I've been exhausted so my fiancé told me it was time to relax and I didn't need the burden of "finding replacements" so I told my boss. I was done. She begged me to do one day a week until I had the baby and I did agree to that. But now all my coworkers are talking badly of me saying "she's pregnant not dead" when not a one of them have any idea what it's like to be pregnant or have these types of complications!!! Since when was it against the law for me to make decisions for myself!? They are all aware that I've been terribly sick! I'm 37 weeks and have gained 4 pounds!! I also have to have surgery afterwards and they still think I'm playing some game... Any advice?
